Description

Bortle 9 😱 No Filter 😱 No Calibration Frames 😱 One single night 😱

This is Messier 94, the Cat’s Eye Galaxy 🐈‍⬛ Meow 🐈
Well, this was interesting. We NEVER image in broadband from our Vegas backyard, we always thought there was no point because of how polluted the sky is. We had an unexpected clear night and were starving for some deep-sky object, so we set up our telescope in the backyard without really knowing what to shoot. We decided to do something we never attempted before, imaging in broadband from home. We picked a galaxy at random, M94, and decided to make this challenge a little crazier and so used no light pollution filter and did not bother with calibration frames.
Well, I have to say the result is much, much better that was I anticipated. Processing was of course a huge pain, but I really did not expect to have a “great” image in the end. This is just a little over 7 hours of total exposure. The QHY600C is an absolute beast and thankfully the noise was manageable to the point where the image looks really clean overall after several noise reduction processes in PixInsight.
Now I really want to image this object from the desert… or keep going at it from home for many nights 😅

We made a video about imaging this object which you can watch here: https://www.youtube.com/watch?v=HhkboxnW_wE&ab_channel=GalacticHunter
