M27 Dumbbell Nebula 400mm

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 […]

Messier 78

Messier 78, about 1600 LY distant from Earth. Unfortunately I didn’t hit the focus very well 🙁 My coldest night this season… -5°C but it felt like -20°… I never shivered this way before while focusing… I need better gloves and a few more layers of clothes 😉 Details

M97 and M108 (560mm)

Today evening I did a test shot with the EF 400mm f/5.6L and Kenko 1.4x converter at 560mm f/8. Only 24 minutes… in a cloud free phase. With much more subs it could be an interesting combination… Details

M97 and M108 (400mm)

This evening I checked in Stellarium the sky and found this 2 nice objects. M97 Owl Nebula and M108 Surfboard Galaxy. Asking myself why I didn’t found and shoot them earlier… so easy to find with the star Merak 🙂 Details
