  1. Some results from the past 2 nights taken using the Spacecat 51 and my Nikon D810a and QSI583ws camera's. I was quite happy to make some imagery again. The WO Spacecat is really a great performer and gives very nice results even with the full-frame D810a. I also like the view of M27 a lot in the huge starfield. This shows how these objects are almost like pasted on the starry background. NGC1499 California Nebula: 24x1200s Ha - QSI583ws / Spacecat 51 SH2-119 (near NGC7000): 5x1200s Ha - QSI583ws / Spacecat 51 M27: 10x300s RGB - Nikon
  2. This image of the Andromeda galaxy is a combination of imagery taken with my D810a and with a dedicated astro-camera (QSI583ws). In total 17 hours of exposures were used to catch this beautiful galaxy in all its glory. The Andromeda galaxy is the closest sister galaxy of our Milky Way and will merge in the far future with our own galaxy. In the sky this galaxy is about the size of 6 full moons and can be seen with the naked eye from dark locations. Telescope: TMB92ss / WO Spacecat 51 Camera: QSI583ws / Nikon D810a Exposures: 19x300s L / 85x300s RGB 3x300s B / 9x
  3. I even dare to challenge the Annie Maunders prize that is awarded. The rules state that the contender should have processed the image from raw data: The image is just downloadable here: https://www.eso.org/public/images/eso1242a/ I doubt if the artist of this photographed artwork did process the images herself. If you look at the size of the image and resolution I'm almost sure it was just downloaded and made into an artwork.
  4. So basically a photo of an art work has won the category? Sorry, I give up...
  5. Thanks. I fully agree if there would be a separate category. Then it would be clear and much more legitimate. Now it doesn't do right to the astrophotography community in my opinion.
  6. Just don't call it astrophotographer of the year then, but astro artist of the year... If a jury can't judge quality the competition is doomed.
  7. I don't have anything against the photographer in any way. And his site looks ok. The problem is that the jury choose this image as a winner, which is just not what the contest is about. It's this one image which is selected not all his imagery. I'm sorry, but the jury should have done a better job in my opinion. And this is not the first time. Just look up the 2016 winner and you will understand what I mean... This was it btw:
  8. He probably had fun. That's not the issue. The issue is that a jury chooses this as astronomy image of the year...
  9. Bad thing is that it is even not original at all. It's just a copy of an earlier idea I really think the judges should reconsider their decision... Just look here (from 2013) and here https://petapixel.com/2013/12/18/tilt-shift-effect-applied-photographs-cosmos-create-tiny-universe/?fbclid=IwAR3mPah3q5BOq4i8f7ntXuZJ5ES_NeoLQ07jX8Zz9mwnmN0jOmQIGMnYVwU or here: https://imgur.com/a/yZcOB Btw, this is 2 minutes of photoshop work:
  10. Found even more data and combined it all together in this 21 hour exposure:
  11. This image shows a nice overview of all images I took in the region surrounding the Cepheus constellation in the past years. I overlaid the images on a starmap to give an idea of the sizes of the objects. It's only now I realize for example that the Shark Nebula is about the same size as the North America nebula. This puts things a bit in perspective.
  12. The last night of my holiday it unexpected became clear. So I was able to catch more data then expected and extend from 2,5 hours to 7 hours total data. The result is astonishing. This clearly shows how much images can improve by having enough integration time. The top image shows 2,5 hours and the bottom 7 hours in the raw stack without any processing except a stretch in Astropixelprocessor. This is the result using just D810a data which I'm quite happy with:
  13. I used this action set that can be found for photoshop: https://www.behance.net/gallery/15470885/Simple-Beautiful-Borders-Free-Photoshop-Actions
  14. I updated the image using data from the 2 Dark nebulae that I took in the previous years during my holidays in the same location. It became a nice blend I think.
