M27 Dumbbell - first OAG

[rodrigol]

My first image using a C11 Edge HD  with 0.7 reducer and Celestron's OAG. Main camera is ASI1600MC. Guide camera is QHY5L-IIM. I only did 50 x 30s Lights and used master darks, flats and bias from a new library. I recently added a pier to my obsy and have been working on getting the scope and assorted equipment on it into shape for the autumn and winter skies. This was a test of various components of the setup.

The image is far from perfect but I'm quite happy. One mystery for me was that I had to use GRBG as the Debayer pattern to get the colors right.

 

 

Comments are more than welcome!

Very nice image.  

One thought about the debayer. did you rotate the images at all before debayering. I remember this caused me a problem once, so just a thought.

Hi Richard,

Thank you!

Good point about debayering and could explain what is going on. The images where taken as FITS and I didn't use PI to process them where I could have selected up-bottom FITS. I ended up using DSS and testing all the generic debayer patterns until I got the colours right 🙂
