Deep Sky

Again I had to realize that the Elephant Trunk Nebula is very very faint. The modified DSLR captured more colors than last year unmodified, but next time I need more lights. Anyway I’m surprised with the result because it was very high temparature (RAW shows about 30°C sensor temperature) and not 100% clear weather. Details […]

With more focal length it is no more possible to catch the whole Cygnus loop on one image… 400mm seems to be the limit 😉 Details

North America and Pelican Nebula in Swan. First time at 400mm focal length. And again a rewarding target for my modified 70D. Details

Continue to capture the wonderful Cygnus regions… this time region around Sadr. Best to show the advantage of a DSLR modification. The HII regions are glowing 🙂 Details

Finally clear sky after raining the whole day yesterday… a wonderful area in Cygnus constellation: the Crescent Nebula and nebulosity around it. I re-focused 3 times. I started shooting without let the lens cooling down first… I don’t know if the low temperatures was responsible for de-focusing… Details crop 2x drizzle:

Yesterday I shooted M92 cluster because no other object was well in sight. Until 0:30h CET. M27 came in perfect position so I decided to stop M92 shooting, and I switched to M27 at the same settings (400mm, f/5.6, ISO1600, 120s). This way I was able to use the darks and bias frames (taken after […]

First light for my new Bahtinov mask. I’m very happy with it. Much sharper result than the last M57 image. This time at f/6.3, ISO800 and only 60sec. M57 is a planatery nebula. 2300 LY away from Earth. The nebula emissions contains expanding and glowing ionized gas, expelled from red giant stars in the last […]

Finally on the sky, M57 Ring Nebula 🙂 First time at 400mm. I’m happy with the result but 400mm is to short. Details Drizzle 2x integration: Normal integration:
