Kurt WOLFARTSBERGER has studied at the Technical University of Vienna mechanical engineering (Dipl.-Ing.) and since Highschool (Bundesrealgymnasium in Steyr) time his hobby is astronomy. His parents have always supported him very much so far and bought a small refractor telescope from KOSMOS 50/500 mm for me, which I often used during night time to observe some moons of planet Jupiter. I also have found a hobby astronomer collegue in Steyr, who has built his own oberservatory in the garden: Wilhelm AURACHER. And he was very professionel in grinding and polishing of lenses and mirrors for selfmade telescopes. I purchased from him my first Newton mirror telescope 100/1000 mm. One of his selfmade telescopes today is still running at the Gahberg oberservatory in Weyregg of 'Sternwarte des Astronomischen Arbeitskreises Salzkammergut', were I became a member of since my retirement. I have also close contact to Josef HAGER, who is very active at the Gahberg observatory. I had the chance to use one of his telescopes a Newton N200 - 800 mm F4, which I have used whenever the weather had clear sky for taking photos in the past.

Comet C12P, h-chi in Perseus, M 42, M 45, M 52 and Zeta Ori February 5th, 2024
February 5th, 2024 I have made some Astrophotos again. First of all the comet C12P/Pons Brooks, but the seeing was very bad because of cirrostrati clouds, and lateron the location of the comet was too low. Only photos with exposure times less than 50s were possible. At that time I also took the pictures of the open star cluster M 52 and the double star clusters h-chi in constellation Perseus - again only exposure times of 30 s. Two hours later the seeing improved a lot so the photos from Zeta Ori and the horse head nebula IC 434 and NGC 2023 as well as the Plejades M 45 and the great Orion nebula M 42 allowed exposure times of up to 140s). In use again the refractor telescope APO115-805 mm with camera NIKON Z6 including flattener TSFLAT25del as well as the mount SW EQM35 Pro. The comet C12P/Pons-Brooks is still located in the constellation of Swan close to star 79 Cyg and has mag 9.0 only - again too low for a photo taken inside a city with short exposuretimes only.
The two comets C12P/Pons-Brooks and C144P/Kushida January 29th, 2024
January 29th, 2024 there was clear sky. In use the refractor telescope APO115-805 mm with camera NIKON Z6 incl. flattener TSFLAT25del. The comet C12P/Pons-Brooks in constellation Swan has an apparent mag of 9.5 - the tail is only rudimentally visible directing to 2 o'clock direction. Comet C144P/Kushida in constellation Taurus has significantly less apparent magnitude with approx. mag 11.3. Exposure times from 1 and 2 minutes were neccessary. The Plejades M 45 (Seven Sisters) show with exposure time of 130s already the blue nebulas around the stars. Finally a picture of the large moons of planet Jupiter dated 29. 1. 2024.
The moon close to Plejades January 20th, 2024
January 20th, 2024 at 8 pm the moon stands close to the Plejades (seven sisters). I have used my camera NIKON Z6 with the zoom lens 70 mm. The problem is the different Light intensity of the two targets moon and star cluster: therefore I have used two different photos with different exposure times, from moon (1/1000 s) and Plejades M45 (5 s) M45 photo one day later without the moon and combined the photos (see the simulation).
Comet C12P/Pons-Brooks December 3rd, 18th and 30th, 2023
December 3rd, 2023 was a clear and ice cold night - minus 11 degrees Celsius and only partly clear sky. I have used the APO115-805 mm on the mount EQM35 Pro and camera NIKON Z6 with flattener TSFLAT25del. The comet C12P/Pons-Brooks is now in the constellation Lyra, below the main star Vega and is a periodic comet of our solar system with approx. 71 years orbital circulation time. The distance to earth is now approx. 385 mio km and his closest position to earth and sun (Perigeum and Perihelion) will be in April 2024. Just now the apparent magnitude is 10 mag, only pictures with exposure times of 30s were possible because of bad seeing conditions. For April 2024 the forcast is mag 4-5 and it will come 0.78 AU (117 mio km) close to the sun.
Comet C2023 H2 Lemmon November 6th and 8th, 2023
November 6th, 2023 evening was a clear sky and therefore I started to take photos of comet 2023 H2 Lemmon. Equipment was the APO115-805 mm on the mount EQM35 Pro and camera NIKON Z6. The comet was moving rather quickly so I took photos at 6:31 PM (left) and 7:44 PM. The third photo shows the comparison and the movement of the comet in approx 1 h and 15 minutes. All single frames shot with an exposure time of approx 1 minute and stacked lateron. Camera NIKON Z6 in main focus together with flattener TSFLAT25del. November 8th, 2023 I have used the RCC telescope 203-1080 mm.
M 17 Omega-nebula, M 16 Eagle-nebula and M 22, September 9th and 10th, 2023
September 9th and 10th, 2023 the seeing was medium range only, because some cirrus clouds were hanging around the sky. Nevertheless I have aligned my APO115-805 mm refractor telescope. The Omega nebula M 17 was the first target, but only frames with less than 50 - 60 s were possible. The globular star cluster M 22 and the galactic star field M 24 in constellation Sagittarius were the next targets and next day M 16 the Eagle nebula. All single frames with less than 1 minute exposure time were stacked. Camera NIKON Z6 in main focus with flattener TSFLAT25del.
Again comet C2023E1-ATLAS
August 19th and 20th, 2023 there was clear sky and a good opportunity to take a photo of the comet C2023E1-ATLAS in the constellation swan (Cygnus) (photo left hand side from August 20th, 2023). The apparent magnitude was between mag 11.8 to 11.9 und the comet was moving fast. I again used the refractor telescope APO 115 - 805 mm with flattener TSFLAT25del. Other photos were shot from the two globular star clusters in constellation Hercules M 13 and M 92 - the other galaxies nearby M 92 are of mag 14th class, M 27 (Dumbbell nebula - constellation Vulpecula) and the globular cluster M 3 in Canes Venatici. The open star cluster IC 4665 in constellation of Ophiuchus and the star cluster and nebula C 20 in swan were the next targets. Finally again a shot of M 8 in constellation Sagittarius, the Laguna nebula. All single shots with approx. one minute exposure time were stacked to combined photos. Camera NIKON Z6 in main focus.
ASTRO-photos dated August 10th and 11th, 2023
August 10th, 2023 I have used my RCC telescope with Reducer (1080 mm focus length) to look for the comet C2023E1 (ATLAS). The comet has changed to the constellation of Cepheus and now has an apperent magnitude of mag 11. I took photos also from M 51 (Whirlpool galaxy), the globular star cluster M 22 and the open star cluster M 11, both located in the constellation of Sagittarius. The day after the weather again was clear, but from time to time some small cirrostratus clouds were in the sky. I used this time the refractor telescope APO 115 - 805 mm and took the following photos: again comet C2023E1 (ATLAS) - again mag 11, but this time located close to the open cluster M 39 in constellation of Cygnus (swan), M 8 and M 20 - Laguna nebula and Trifid nebula in constellation of Sagittarius and i have checked the Supernova SN2023ixf in the galaxy M 101 - pinwheel galaxy (photo left side) - it seems to be a little less intensive than in the beginning in my 2023. All photos using the mount SW EQM35 Pro with camera NIKON Z6. Exposure times between 1 to 2 minutes werepossible. The results are stacked.
The comet C2023E1-ATLAS, July 19th, 2023
July 19th, 2023 again the comet C2023E1-ATLAS in the constellation dragon was target for some photos. This time the apparent magnitude was given to mag 8.7 and again the refractor Telescope APO 115-805 mm with TSFLAT25del was used. 18 single photos with a total exposure time of 1950 s (33 minutes) were stacked together. Camera NIKON Z6 in main focus.
The Laguna nebula M 8, July 14th, 2023
July 14th, 2023 I have taken photos of the Laguna nebula M 8 in the constellation of Sagittarius on e of the star richest regions of our Milky Way. Close next to it the so called Trifid nebula M 20 in red and blue. Both nebulas are accompnied of star clusters. Next I have checked the Supernova SN2023ixf in the pinwheel galxy M 101 - can be seen very good still. The Globular star cluster M 3 in Canes Venatici at the end. I used the nwe refractor telescope APO 115-805 mm with the flattener TSFLAT25del. The single photos have an exposure time of 90 to 100 sec each an d are stacked together. Mounting SW EQM35 Pro and camera NIKON Z6 in main focus. All pictures reduced to 2000 pixel.
The comet C2023E1-ATLAS, June 25th, 2023
June 25th, 2023 I have made a photo of the new comet C2023E1-ATLAS in the constellation Ursa Minor again. The apparent magnitude today was given as mag 10.0 and I used again the new telescope APO 115-805 mm with flattener TSFLAT2. Twelve single photo shots with a total exposure time of 1020 sec (17 minutes) were stacked together. The moon this time showed a period of 45% waxing. After that I took photos of the galaxies M81 / M82 and M 108 with planetary nebula M 97 - the Owl nebula, as well as the globular star cluster M 4 in the constellation Scorpius. A comparison with the picture of yesterday shows the track of the comet from 24th until 25th of June 2023. Again I used my mount SW EQM35 Pro and the camera NIKON Z6 in main focus.
New comet C2023E1-ATLAS, June 24th, 2023
June 24th, 2023 I catch the new comet C2023E1-ATLAS in the constellation of Ursa Minor. It has an apperent magnitude of mag 10.2 and I have used the new telescope APO 115-805 mm as first light. 21 single exposures with an exposure time of approximately of one min I have stacked together. The moon as a little game spoiler with 35% waxing was there. I include a photo of the moon. As always I have used my mount SW EQM35 Pro as well as camera NIKON Z6.
Photos taken from Galaxies M 51, M 101, M 108 + Owl nebela M 97 and GC M 4, June 12th / 13th, 2023
June 12th/13th 2023 the seeing was very good and no moon in the sky. Therefore I have used my Skywatcher APO ED80-600 mm with Flattener TSFLAT2 mounted on EQM35Pro and camera NIKON Z6. First target was M 51 the Whirlpool galaxy (photo on the left). Then I have checked the supernova ixf in the pinwheel galaxy M 101 - it is still good visible. Next to M 108, the surfboard galaxy and left from the galaxy the owl nebula M 97 in blue. Then to the south to the constellation scorpius close the the main star Antares we can see the globular cstar cluster M 4. It is really amazing how many details you can see with the small 80 mm refractor without moonlight and good seeing. This time exposure times of 90 s were possible. All photos are stacked of course. - Next day photo of the planet Venus taken by the Maksutov M100/1000 mm telescope - sun shine from the side, so you can see a clear sickle form of the planet.
Supernova in galaxy M 101 photo captered, May 27th, 2023
May 19th, 2023 in the galaxy Messier 101 - Pinwheel galaxy - in the constellation Ursa Major a supernova was discovered by a Japanese amateur astronomer. The magnitude of the supernova is 10.8 the galaxy has mag 7.9 and is seen from the top (90 degrees) so the spiral arms can be seen perfectly. The size is approx. double as our milky way galaxy and the distance to earth is 21 mio lightyears. I used the Newton telescope N200-800 mm owned by Sepp Hager together with the Nikon Z6 camera and shot 12 single photos with exposure times from 30 to 60 sec. A game spoiler was the moon with 52% waxing and rather close to the location of M 101. So it was not easy to take the photos.
Moon with light from earth and galaxies in constellation Lion from May 21st, 2023
May 21st, 2023 finally it made it - after a long period of rainy and bad weather conditions a clear night has come. I used my RCC with reducer for a focal length of 1080 mm mounted on EQM35Pro with Nikon Z6 camera - after alignment and checking the polar adjustment. First the moon - 5% waxing with excellent reflction light from the earth - picture to the left. Then constellation Lion with a group of approx. 24 galaxies all having a distance from earth of approx. 35 to 45 mio Lightyears. I took a photo of the so called Lion triplet including the galaxies M65, M66 and NGC3628, next M105 with NGC3371 and NGC3373 and M96 and M95. At end of session the two open star clusters M44 (distance approx. 600 lightyears) and M67 (distance approx. 2700 lightyears) in the constellation Cancer. Both open star clusters include approx. 500 indiviual stars. All pictures stacked from single shots of 30s exposure times.
Conjunction of planets Jupiter and Venus March 1st, 2023
March 1st, 2023 there was a conjunction of the planets Jupiter and Venus, visual distance 0.6 degrees only. Planet Venus overtakes planet Jupiter on the right side (see also the picture below showing the planets location February 22nd, March 1st, 2nd and 4th, 2023). The picture on the left was made with the refractor teleskope ED80-600 mm, where you can see the four large moons of Jupiter (lined up from top to down: Callisto, Ganymed, Io, Jupiter and Europa). The planet Venus on the right side is much brighter than the planet Jupiter. Both cameras NIKON Z6 with 70 mm zoom lens and SONY alpha58 with tamron zoom 18 - 250 mm as well as the mounts SW EQM35 PRO and Omegon LX3 were used.
Sun spots dated February 28th, 2023
February 28th, 2023 I have shot photos of the sun spots with the refractor telescope ED80-600 mm using a special sun filter using the camera NIKON Z6 and ISO 400. For comparison reasons the NASA SDO picture - copyright NASA is shown below.
Conjunction of planet Jupiter, moon and planet Venus February 22nd, 2023
February 22nd, 2023 approx 18 hrs there was a rare meeting in the sky of two planets and the moon. Unfortunately some misty clouds were hanging around in the sky but you could see planet Jupiter and planet Venus and in between the waxing moon at 7% lumination. I was taking photos with the two cameras NIKON Z6 70 mm lens annd SONY alpha58 with tamron zoom lens 18 - 250 mm in the dawn. The picture of the moon, lit by the earth reflected sun light was taken with 250 mm zoom lens - picture rather unclear because of cirrostratus clouds.
Orion nebula M 42, Plejades M 45 and triangulum galaxy M 33 February 21st, 2023
February 21st, 2023 there was excellent clear sky conditions - therefore I have used my RCC200 with TS CCD47 Reducer lens (1080 mm focus length) mounted on my EQM35. First a short visit to the comet C/2022E3-ZTF, now located nearby the constellation of Orion the hunter. With a magnitude of 7.1 it has reduced the light intensity again, no wonder his distance to earth now has increased to 0.75 AU approx. 110 mio kms. Next to M 42 the Great Orion nebula, M 45 the Plejades seven sisters with blue nebulas sourrounding and to the triangulum nebula M 33, which is in reality s galaxy like milky way but not easy to catch with the camera. The seeing developes excellent because no moonlight pollution enabling exposure time of one minute and more and this close to the city center.
Comet C/2022E3-ZTF dated February 16th, 2023
February 16th, 2023 it was clear sky but many misty clouds. I wanted to take a picture of the comet before he will disappear to 'Nirvana' and he will return to our Solar system in approx. 50,000 years only. I used my refractor telescope ED80-400 mm with flattener and shot an overlook photo with my camera NIKON Z 6 mount LX 3 and the 70 mm zoom lens (this time with mouseover description). The comet C/2022E3-ZTF today had a manitude of approx. 6.6 mag and remarkable reduced light intensity. He is located on the left side of Aldebaran - the main star in the constellation Taurus same distance as to the star Epsilon Tau but the opposite side. On the left again the photo of the comet this time with an exposure time of 20 s for the single picture because the seeing was rather bad. In sum it gives an eight minutes photo after stacking.
Again comet C/2022E3-ZTF and M 42 dated February 13th, 2023
February 13th, 2023 there was clear sky again but also misty clouds which disappeared at midnight only. I used the N200-800 mm Newton reflector telescope with corrector lens and with the NIKON Z 6 camera mounted on LX 3 I made the situative photo. The comet C/2022E3-ZTF this time trailed close by the open star cluster NGC 1647 having an apperent magnitude of 6.1. On the left side again the photo of the comet, but this time 15 s exposure time for the single picture only, because of the bad seeing conditions. In sum gave a 300s shot. I made another photo of the great Orion nebula M 42 with the N200 (single shot 25s - in sum 275 s). All pictures reduced to 2500 px for web reasons.
Again comet C/2022E3-ZTF and M 42 and M 45 February 12th, 2023
February 12th, 2023 surprisingly clear sky in the evening and no moon. A good opportunity for my ED80-600 mm to catch some photos. I also tried the flattener lens from RCC telescope with the refractor with success. First of all the overlook photo with camera Z 6 and 70 mm lens to locate the comet for today. On the left side the photo of the E3-ZTF (mag 5.8) because of good seeing this time with an exposure time of approx. 60 s. I also used the opportunity of good seeing with two more photos of M 42 (Orion nebula - 10 x 30 s) and the open star cluster M 45 of the Plejades (30 x 64 s). The Plejades photo first time shows the blue background nebulas sorrounding the stars. All photos are reduced in size for website reasons to 2000 px.
Comet C/2022E3-ZTF track alalysis February 10th, 2023
February 10th, 2023 I have mounted the camera NIKON Z6 on my LX3 and shot a photo with the 70 mm lens - the basis for the track analysis of the comet. The past locations are recorded with photos and the future is taken from the map Cartes du Ciel. The comet bypasses the planet Mars on February 11th very close.
The great Orion nebula M 42 February 9th, 2023
February 9th, 2023 i used my Richie Cretien Cassegrain telescope RCC200-1624 mm mounted on the SW EQM35 Pro together with the camera NIKON Z6. In the constellation Orion I took a photo of the great nebula again - so I made a photo two days ago with the Newton N200-800 mm. This time single shots with 30 s were possible because no moon poils the sight. The seeing was good and for comparison reasons the former picture from two days ago is enclosed.
Comet C/2022E3-ZTF February 5th, 6th, 7th and 9th, 2023
February 5th, 2023 I have used the refractor telescope ED80-600 mm with SW EQM35 Pro mounting and the camera NIKON Z6. The seeing was very bad, because the full moon and many cloud stripes were around the sky. The photo to the left shows the comet nearby the main star of constellation Auriga - Capella. The apperent mag of the comet is approx. 5.7 mag, and the tail is difuse. Exposure time of a single photo is 10s only because of the bad seeing. February 6th the seeing was much better, only the moon and city light were a killjoy. Exposure time of single photo 15 to 20s. App. magnitude on February 6th was 5.85 mag - the comet enlarges the distance to earth more and more (distance now to earth approx. 50 mio km). February 7th single shots with 25 s were possible and February 9th even 30 s - today I got the best shot of the comet.
Andromeda galaxy M 31 - 7. 1. 2023
January 7th, 2023 I have used my refractor-teleskope ED80-400 mm - including focus length reducer - on the SW EQM35 Pro mounting and camera NIKON Z6. The picture shows the Andromeda galaxy Messier 31 - with a distance from earth of 2.5 mio light years. The picture also shows the two small fellow galaxies M 32 (above left to center of M31) and M 110 (below center). The single photo had an exposure time of 25s because of bad seeing conditions (moon and city light), followed by stacking to 5 x 500s. M 31 has an apperent magnitude of 4.4 mag and is the only galaxy you can see with the naked eye, when good seeing conditions are available.
Moon and Jupiter, Dec. 28th, 2022 and Jan. 1st, 2023
December 28th, 2022 I have made a photo of the waxing moon - 35%. Telescope RCC200-1624 mm, camera NIKON Z6. The second photo waxing 75% I have shot on New Years eve with the refractor telescope APO ED80-600 mm again camera NIKON Z6. Photo of planet Jupiter with the four large moons (left Europa - (Jupiter) - right Io - Ganymede and Callisto) - you can see also many backgrounds stars. Exposure time for Jupiter 1.6 s.
Moon and planet Jupiter, November 27th, 2022
November 27th, 2022 at the beginning evening it looks not so bad. I took some photos of the moon - waxing 18 - 19% - using the refractor telescope ED80-600 mm and camera NIKON Z6. But near to the horizon clouds of fog were appearing more and more and also the humidity was very high. So i took a quick photo of planet Jupiter (see the moons Europa, Ganymed and Kallisto to the right and leftside out the moon Io). At 8 pm all was fog. Sorry - I packed all equipment away.
Again in use NIKON Z 6, November 21st, 2022
November 21st, 2022 suddenly the fog ans clouds disappired and there was clear sky until 11:30 pm. I used my SW EQM35 Pro mounting together with the refractor telescope ED80-400 including reducer to shorten the focus length to 400 mm. The socalled Northamerica-nebula NGC 7000 in constellation swan is to be seen on the left side photo. A few degrees upwards the open cluster M 39 again in swan - we inside the milky way - therefore the impressive large number of stars can be seen. The main star Altair in constellation Eagle (Aquila) and the open star cluster M52 with Nova Cas 21 and the nebula Caldwell C 11 on the next picture. All photos with camera NIKON Z6 - ISO 2000 and 30s exposure time, all pictures stacked.
New camera in use, October 25th, 2022
October 25th, 2022, after the partial eclipse at noontime the new camera NIKON Z6 was in use. Together with the Newtontelescope N200 F4 from Sepp Hager I took photos of the clobular cluster M 13 in the constellation of Hercules, globular cluster M 56 and Ring-nebula M 57 - both in the constellation of Lyra and last but not least again a picture of the double star system of Albireo in the constellation of Swan.
Partial eclipse at October 25th, 2022
October 25th, 2022 at noontime there was a partial eclipse to observe in Steyr, Austria. Start at 11:15 am MEST ending approx. two hours later. The maximum with 25% was 12:20 pm. I have used the APO ED80-600 refractor mounted on SW EQM35 PRO. Camera SONY alpha 58 with ISO 200. Exposure time 1/800 sec.
Again Newton N200 F4 dated July 19th, 2022
July 19th, 2022 evening again the Newton telescope N200-800 mm F4 from Sepp Hager was in use. The Lagoon-nebula M 8, Trifid nebula M 20 as well as the open star clusters IC 1287, M 11 (left photo - so called 'Wild Duck Cluster') and the globular star cluster M 13 in constellation Hercules were targets. The Ring-nebula M 57 in constellation Lyra and the double star Albireo in Cygnus (swan) were observed, the two components shining in different colors (red and blue).
The Lagoon nebula M 8 -
The Trifid nebula M 20 -
The open star cluster IC 1287
The globular star cluster M 13 in Hercules - The Ring nebula M 57 in Lyra
The double star Albireo in swan - visual distance 35 arcminutes
Comet C2017 K2 visits M10 on July 15th, 2022
July 15th, 2022 the comet C2017 K2 (Panstarrs) has visited the globular star cluster M 10 in the constellation Ophiuchus. The picture was made with the refractorteleskop ED80-400 mm with focus length reduction (F5). The seeing was in a medium range until the moon rises at 11:15 pm. The globular star cluster M 10 has approx. 14,500 light years distance to earth and has an apperent mag of 6.6. The comet is mag 11 - distance to earth of 270.5 mio km - and is on the limit of the small telescope. The picture was stacked from 5 single photos ISO 800 with an exposure time of 30 sec each.
Galactic nebulas and star clusters observed July 2nd to 3rd, 2022
Evening of July 2nd, 2022 the Newton 200-800 mm from Sepp Hager again was in operation. Unfortunately the seeing was not so good as last week. The photo left hand side shows the 'Lagoon' nebula M8, this time with the 8 inch reflector telescope with 800 mm focus length. The other pictures are M16 ('Eagle Nebula'), M17 ('Omega' or 'Swan' nebula), M20 ('Trifid' nebula) with star cluster M21, the globular star cluster M22, the star cloud M24 and the open star cluster M25. At 2 am the observation was stopped by setting clouds. All photos are stacked from single exposures taken by the camera SONY alpha58, exposure time 30 sec and ISO 1600.
Pictures of nebulas and star clusters from June 25th to 26th, 2022
Despite smoke production during the fire works of the 'Steyr Stadtfest' around midnight there was an excellent seeing in the city, so I could see the milky way in the town area in my garden. So I decided to use my refractor telescope ED80-400 (with focus length reduction to 400 mm - F 5) to get some sensationell photos. Starting (left side photo) with the 'Lagoon' nebula M8 in the constellation Sagitarius; this photo shows on the left hand side below also the globular star cluster NGC 6544 ( app mag = 9) and on the top a part of the 'Trifid' nebula M 20, located on top of the picture showing the red / blue color I find very impressive, and on top left the open star cluster M 21. The next picture shows the two globular star clusters M 4 (app mag = 5.6) und NGC 6144 (app mag = 9.6) around 'Antares' - main star of constellation Scorpio, as well as the globular star cluster M 10 (mag = 6.6) in constellation Ophiuchus and M 11 (Wild Duck open star cluster mag = 5.8) in constellation shield; the galactic 'Omega' nebela M17 in constellation Sagitarius formed the end of my star trip - the moon rises. All photos are stacked from single exposures taken by the camera SONY alpha58, exposure time 30 sec and ISO 1600.
New photos from galaxies M 51 and M 101 dated June 12th, 2022
June 12th, 2022 even close to the full moon I have again tried the Newton F4 200-800 mm from Sepp Hager. This picture was derived from 20 single photos with exposure time of 30 s, in total 10 minutes. Next target was the pin wheel galaxy M 101. Both galaxies have an approx. distance from earth of 20 Mio light years and have an appernet magnitude of 8.4 mag (M 51 - 23 mio ly) and 7.9 mag ( M 101 - 21 Mio ly ).
New ASTRO-photos dated from May 18th, 2022
May 18th, 2022 the Newton F4 200-800 mm telescope from Sepp Hager was ready for new photos. The three galaxies in the constellation of Leo M 66, M 65 and NGC 3628 I had alteady last year selected for a photo. They are also knowns as the LEO-Triplet, because they form a group in a distance to earth of approx. 35 Mio light years. This photo was stacked in total of 54 single pictures (30 sec each) - total exposure time of 28 min (photo to the left). The open star cluster M 67 ii the constellation of cancer has a distande to earth of 3,000 light years with an apperent magnitude of 6.1 mag. This picture again was stacked from 30 single photos each 20 sec exposure time giving in total apprtox. 10 minutes. Last but not least a very interesting object: M 60 and M 59 are galaxies and close to M 60 is the galaxy NGC 4647 - one star in this galaxy exploded in a socalled SUPERNOVA. The distance to earth is 61 Mio light years and the bright star can be seen in the detailed photo. Total exposure time approx. 15 minutes.
The crab nebula M 1, March 1st, 2022
March 1st, 2022 again clear sky, no clouds - the mount is ready expecting dawn will darken the sky. The mount will be adjusted with ED80 refractor and 2-star method. First target is Mirach in constellation Andromeda and some quick photos. Also the galaxy M 33 photos taken by APO ED80. Then change to RCC 8 inch with 67% reduction lens. Mirach with NGC 404 (ghost) is the first target (2,05 mag - 200 lightyears -- NGC 404: 11,5 mag - 10 mio lightyears, distance to Mirach 7 arc minutes). Then the open star cluster M 52 in constellation Cassiopeija - the NOVA star from 2021 still good visible. Search for M 33, but not found. Next via Plejades to M 42 - the Great Orion nebula, taking some more photos: Then the crab nebula M 1, a supernova remnant some 1000 years ago, dicovered by chinese astronomers, they called it a 'guest star' - photo on left hand side (8,4 mag - 6,500 lightyears). Last Targets are the open star clusters in constellation Auriga, M 38 with NGC 1907, M 36, M 37 and M 35 with NGC 2158 in Gemini. All photos from RCC with reduced focus length to 1088 mm. 'Baby, its cold outside', some degrees below zero - I decide for: GAME OVER !
Photo of great Orion nebula M 42, February 12th, 2022
February 12th, 2022 again good weather, only the moon light was rather strong and hindering good astro photos. Nevertheless my refractor telecope APO ED80-600 mm with SONY alpha58 mounted on EPM 35 Pro and SONY A 100 with tamron 15 - 250 mm zoom lens on LX 34 were ready again. The great Orion nebula M 42 was the first target - during wintertime a highlight object for each astronomer. Also the open star clusters in the constellation Taurus, the Hyades with main star Aldebaran and the Plejades ( M 45 ) were good targets to find. Both pictures were taken by the SONY alpha camera A 100 with a tamron zoom lens ( 90 mm resp. 250 mm ). Finally the open star cluster M 52 in the constellation of Cassiopeja with the NOVA star from year 2021. --- Another two pictures from M 42 taken on 23.2.2022 - clear sky and no disturbing moonlight. First picture take with APO ED80-600 mm and the second with 8 inch RCC with focus length reduction to 1088 mm.
Photo of Andromeda galaxy M31, February 9th, 2022
February 9th, 2022 no clouds the whole day - time for my refractor telecope APO ED80-600 mm with camera SONY alpha58 to be active. Already during daytime I started with the sun spots (photo below). You can see the comparison between the NASA photo from SDO (Solar Dynamics Observatory) and my ED80. The next photo from planet Jupiter setting between the trees and crows very early during dawn. Then the moon waxing at 61% illumination. With the 67% reduction lens my telescope reaches 402 mm focal distance: ideal for catching the entire Andromeda galaxy M31 with her neighbors M32 and M110, standing now high in the western sky. Unfortunately the moon was very close so the exposure time was limeted to 25 sec because of the moon light disturbance. Last picture of Mirach (Beta Andromeda) with his 'ghost' - a red giant star (apparent magnitude 2,1 mag) and a distance of approx. 200 light years and in distance of 7 arc minutes the small elliptic galaxy NGC 404 (distance from earth 10 Mio lightyears - apparent magnitude 12,54 mag). Thats why it is not so easy to take a good picture because the bright Mirach outshines the small galaxy very easy. Nevertheless the 'ghost' galaxy NGC 404 is good visible.
Sun spots at winter begin, December 21st, 2021
December 21st, 2021 beginning of winter. I have observed the sun spots and took a picture. Camera SONY A 100 - Telescope M 100 - 1000 mm with sun filter. Comparison with SDO from NASA of course without atmosphere (copyright NASA). Next day telescope APO ED80 - 600 mm and camera SONY alpha58.
Evening star planet Venus, November 23rd, 2021
November 23rd, 2021 I have catched the evening star Venus with my SONY alpha58 camera in the dawn period. The detailed picture was taken with my Maksutov telescope MCX127 with 1900 mm focus length and the camera SONY alpha 58 using a 2x digital zoom. The planet shows a moonlike sickel-shape with 40% lighting. Unfortunately the air condition was not good. - December 3rd 2021 the air quality was better (tamron 90 mm - 85 mm - 55 mm).
Sun spots photo, October 29th, 2021
October 29th, 2021 a photo of the sun spots using the refractor telescope ED80-600 mm with Sony alpha58 in main focus.
Photo of M 57 Ring nebula in the constellation Lyra, clobular clusters M 56 (Lyra) and M 92 (Hercules), September 24th and 25th, 2021
September 24th and 25th, 2021 I have made photos of M 57 Ring nebula in the constellation of Lyra and from the clobular star clusters M 56 (Lyra) and M 92 (Hercules). I have used my refractor telescope SkyWatcher ED80-600 mm mounted on EPM 35 PRO together with the camera SONY alpha58 in main focus. - The picture left shows M 57 the Ring nebula in the constellation of Lyra. The origin was approx. 20,000 years ago when a star collapses by explosion and lost the outer region of itself. Today shows up as a socalled Planetary nebula in a distence from earth of 2,300 light years having an apparent magnitude of 8.8 mag. --- The globular star cluster M 92 in the constellation of Hercules has an approx. distance from earth of 27,000 light years with an age of about 13 billions years. The apparent magnitude is 6.3 mag - good visible with normal field glasses. Another picture from constellation Lyra showing the globular star cluster M 56, distance from earth approx. 33,000 light years and apparent magnitude of 8.3 mag. All pictures are stacked from single photos of exposure times of 20 to 30 seconds. Total exposure times ranging from 100 to 220 seconds.
Picture of globular star cluster M 13 in the constellation of Hercules, September 6th, 2021
September 6th, 2021 I have made a photo of the globular star cluster M 13 in the constellation of Hercules. The telescope was the refractor from SkyWatcher ED80-600 mm mounted on EPM 35 PRO and camera SONY alpha58 in main focus. Exposure time 120 x 25 s stacked. - The globular cluster M 13 in the constellation of Hercules has an approx. distance from earth of 22,000 lightyears and is about 11 billion years old. The apparent magnitude is 5.8 mag - good seeing conditions make it visible for the unaided eye.
Both pictures of the moon taken by telescope MC 100/1000 mm, exposure time 1/250 s in main focus of SONY alpha58.
View to the Universe, June 4th, 2021
June 4th, 2021 succeed to view to the distant universe. Telescope: APO ED80-600 mm mounted on SkyWatcher EQM35 - camera SONY alpha58 in mainfocus. - The picture shows the socalled 'LEO-Triplet', three distant galaxies in the constellation LEO - M65, M66 and NGC3628. The photo was stacked from single pictures with an exposure time of 45 sec with ISO 800, total exposure time around 68 minutes. The three galaxies form a group in a distance from earth of approx. 35 millions lightyears with an age of more than 13 billions years. Magnitude 9 to 10 mag, diameter 100,000 Lys. - July 12th, 2021 I had the chance to catch the globular star cluster M3 in the constellation canes venatici; the distance to earth is some 40,000 Lys - it is therefore part of our galaxy (milky way) - it contains approx. half a million of stars and the diameter is some 90 Lys. The apparent magnitude is 6,2 - therefore cannot be seen with the naked eye. Seven single photos taken with 30 sec exposure time, which results in a total time of 210 sec.
'Messier'-trip in constallations 'Taurus-Auriga-Cancer-Perseus' on April 11th, 2021
April 11th, 2021 clear sky developed in Steyr when the sun sets and there was a good chance for astro photos because the moon was invisible. I have used my refractor telescope ED 80-600 mm on the Skywatcher EQM35-mounting together with SONY alpha58 in main focus. After adjusting the mounting (with 2-stars methode) the first catch was M45 (Plejades) in constallation Taurus, even during dawn period (blue background) photo left hand side. Continued by the open star clusters M38 with NGC 1907 and M36, M37 and M35 with NGC 2158 right below M35, a side step to the nebula M1, a Supernova remnant from 1000 years ago, M44 in constallation 'Cancer' and Open Twin star cluster h and chi in 'Perseus' (also NGC 884 and NGC 869), where a small meteor or satelite joined on the picture. Exposure times always between half a minute and 90 seconds. Finally a photo from the planet 'Mars', travelling his way along the constallations 'Auriga' and 'Taurus'. - Charles Messier was an astronomer who issued his catalogue of more than 110 important objects of the sky all named with Mxx - Messier. NGC stands for New General Catalogue.
Mond and planet Mars form a magic square in constallation 'Taurus' March 18th, 2021
March 18th, 2021 planet Mars, the Plejades (M45), moon and the main star of constallation Taurus Aldebaran in the open star cluster of Hyades form a magic square. Although the weather was very bad I was really lucky when the clouds open up for a short period and i could catch the photos. I used my SONY alpha58 camera on the omegon LX3 mini mounting. Exposure time approx. 1 minute. The moon was rather bright with 24% , so it was not easy to catch the picture. You can also see the way the planet Mars has travelled through the 'Golden door of ecliptic'.
Planet Mars travels through 'Golden door of ecliptic' March 6th, 2021 and following days
Starting beginning of March 2021 the planet Mars is located mearby the Plejades (M45) and passes then the so called 'Golden door of ecliptic' in the constallation of Taurus. For this purpose the planet Mars travels between the two open star clusters of Hyades including the main star of Taurus Aldebaran (a red giant star) and the Plejades. Aldebaran (distance from earth 67 light years) has 1.16 times the mass of the sun, but his diameter is more than 45 times that of our sun and the illuminating power is 150 times that of the sun. On the photo left side you can see the red color light of planet Mars (called the 'red planet') in comparison to the stars of the Plejades, which are relative younger stars and shining white. The distance of Plejades open star cluster is approx. 1,350 light years, the Hyades's distance - also an open star cluster - is 151 light years. All pictures made by SONY alpha58, on mounting SkyWatcher EQM35. Exposure times approx. 3 minutes.

Astro - photos from February 22nd til 26th, 2021
From February 22nd til 26th, 2021 there was excellent weather conditions with clear sky a good opportunity for astro photos. One disadvantage was the strong moonlight, avoiding longer exposure times. The sun spots were rather small and not special, the sun is not very active now. But the open star cluster M 45 the Plejades and the great Orion nebula M 42 were a good target. I heve used both SONY cameras alpha A 100 and alpha 58, as well as the camera mounting omegon LX3 for the tele lens tamron 250 mm. The refractor telescope ED 80-600 mm, the Maksutov MC 100-1000 mm and the reflector telescope RCC 203-1624 mm on SkyWatcher EPM 35 mounting were used.
Astro photos February 2021
Earth light photo of the moon February 14th, and two more photos from February 18th, 2021
On February 14th, 2021 and cold temperature of - 5 degree Celsius I made of photo of the waxing moon 8 % with tamron tele 250 mm and camera SONY alpha58 mount omegon LX3 lunar array drive. Exposure time 0.8 sec. The dark side of the moon becomes some reflection light from the earth.
Two more photos taken with refractor AD80/600 on EQM35 mount show the moon 40 % waxing (1/800 sec) and the Orion nebula M42 (exposure time 2 minutes) both with camera SONY alpha58 in the main focus.

Sun spots picture December 27th, 2020
December 27th, 2020 a sun spots picture was taken using a AP80/600 mm refractor telescope. Picture data camera Sony alpha 58 in main focus - exposure time 1/1000 sec. A metal folie was used as a filter. The air was rather unsteady.
Great conjunction - Jupiter and Saturn at December 21st, 2020
Monday December 21st, 2020 17 h MET: my first sight to Gahberg was disappointing, all cloudy and had doubt that we can see anything today. But than the clouds open up at the southwest. I think the pictures say everything. The telescope photo (left) I have downloaded from a livestream from Cosmosapiens - located on the Canary Islands.Trio Dec 21st, 2020
'Great conjunction' - Jupiter and Saturn meet in December 2020
In December 2020 the two large planets Jupiter and Saturn meet very close for a 'Large conjunction' , of course seen from earth only. The two planets have different periods of revolution around sun - thats why this will repeat every 20 years aprox. But so close (only six minutes of arc = one fifth the size of the moon) they meet very seldom. Here a scetch of the orbits of the planets (© NASA APOD). On my photos from December 5th and 7th, 2020 the planets are not so close. Planet Jupiter shows his large moons - right hand side on the photo. Both pictures taken with SONY alpha 58 tele tamron 250 mm and auto tracked by EPM 35. Exposure times is 20 and 10 sec respectively. The pictures from December 14th and 18th, 2020 were taken from a webcam on Gahberg, because it was fogy in Steyr.photo Dec 7th - webcam Dec 14th - webcam Dec 18th
Sunspots on December 2nd, 2020
Am 2. Dezember ist mir ein Foto der Sonne mit der neuen astrocam von Altair GPC 130 C BASIC gelungen. Nach Jahren der Inaktivität der Sonne im Minimum gibt es nun wieder Sonnenflecken - Gebiete mit ca. 1000 bis 1500 grad Kelvin niedrigerer Oberflächentemperatur. Die Camera war auf einem kosmos 50 / 500 mm Linsenfernrohr und auf der sky watcher EQM 35 PRO montiert. Belichtungszeit ca 5 ms. Es wurde ein Metallfolien - Sonnenfilter verwendet. Das Foto wurde aus 3 verschiedenen Aufnahmen zusammengesetzt.

Comet Neowise 2020F3, July 12th, 2020
July 12th, 2020 in Steyr I had the chance to see the comet Neowise 2020F3. Two shots by my Sony alpha58 and the tamron 250 mm lens. At midnight again Jupiter with the four large moons with my MCX 127 and Sony alpha58. Enjoy the pictures.
Full moon and moons of Jupiter, July 5th, 2020
July 5th, 2020 the moon was full again, a shot with Sony alpha58 tamron 250 mm and with telescope MCX 127 /1900 mm planet Jupiter with the large moons Callisto, Io, Ganymed and Europa. Jupiter was located approx five full moon diameters above the moon.
Full moon and planet Venus as a sickle, May 7th, 2020
May 7th, 2020 the full moon and planet Venus were objects for photos. The full moon picture made by Maksutov Cassegrain lens 100 / 1000 mm and planet Venus by Bresser Messier MCX telescope 127 / 1900 mm - Venus already very close to Earth. Both pictures with Sony alpha 58 in main focus.
Planet Venus at the Plejades April 5th, 9th, 2020
April 1st, 2020 at 23:31 MEST - photo of the moon with Bresser Messier MCX telescope 127 / 1900 mm - moon 56 % waxing. The second photo on the right one day later - 67 %. April 5th, 2020 at 20:56 h MEST again a photo of the planet Venus in the open cluster of Plejades. Camera: Sony alpha 58 with tamron 18 - 100 mm, exposure time approx. 40 sec. Another photo of Plejades with Venus - she has made her way up and away from the stars - on April 9th, 2020 21:27 MEST. Camera: Canon EOS with Zoom Lens EF-S 55 - 250 mm, exposure time 55 sec. Both pictures guided by Bresser Messier MCX.
Conjunction Moon - Venus - Plejades, March 28th, 2020
March 28th, 2020 there was a rare constellation shown in the sky: the young moon (four days) meets the planet Venus and open starfield of 'Plejades' in Taurus. The left picture shows the conjuntion at 19:13 h MET short after sunset, but before astronomic dawn (Plejades not be seen). - The second photo taken at 20:25 MET (exposure time approx 10 sec) shows already earth movement (stars no dots but lines); also to be seen is earth's backlight on the dark side of the moon. The Plejades to be seen in the top middle. Camera Sony alpha 58 with tamron 15 - 250 mm.
Merkurtransit November 11th, 2019
November 11th, 2019 after noontime it was after 2016 again the case of a so called Merkurtransit: planet Merkury is positioned between the sun and earth and can be seen as a small black dot before sun. As Merkury is so small it can be seen by a telescope only; a special filter is necessary as the sun is too bright not to damage the eyes. Compared to 2016, this time the weather was bad and cloudy, no free sight to the sun in Steyr. So you had to observe the case via internet from the observatory on mountain Pico del Teide, Canary Islands. The pictures above are from Solar Scope, Canary Islands and their copyright. On the second picture you can see the the view from Solar Scope and the moon is rising in the background.
