Catching up on processing of data captured before I rolled the LX200 out.
This was taken on the easter week-end but this is about my 4th attempt to process - I'm not sure why but but I really struggled with the background. Also the stars are not great - looks like a bit of trailing but guiding was good, PA was good enough and nothing had changed to make flexure any more likely. So any suggestions as to what caused it would be appreciated.
Anyway, its 55 X 180s SW Evostar 80ED, ASI2600mc
full res is here
Scope: Skywatcher Evostar 80ED (SW 0.85 FR/FF) on a SW NEQ6Pro
Guiding; SW Evoguide 50ED, ASI 120mm mini
Meade 8" LX200 GPS on wedge (Guided with a cheapo 50mm guidescope and a ZWO ASI 120mm mini)
Sharpstar 61EDPH II (with dedicated 0.8 reducer) with wiliam Optics 32mm uniguide
Camera: ASI2600MC pro. QHY 163M with ZWO 7nm NB filters, Canon EOS700D astro mod
Secondary mount: Skywatcher StarAdventurer
Beautiful image! That 2600 looks like a wonderful camera!
The last M101 image that I shot a few days ago had a rough background that I had a really tough time with. Lots of chrominance noise and mottling. For some reason (wish that I knew what), I ran through the same linear workflow in PI (dynamic crop, split rgb, linear fit, channel comb, abe or dbe, background neut, EZ decon, and color calib) and ended up with a much better background. I ended up processing in Photoshop though to get more of the look that I was after.
Thanks for sharing more of your amazing Easter weekend!
