Thank you Michael. I do enjoy getting out there trying new things to improve my images. This particular image was a bit of a tester to see where the line of diminishing returns was a far as noise goes. Around 10 hours is the line for me with this setup the extra few were added basically because I had them.
With 5 sessions all taken across similar hours, similar temperatures, almost identical guiding errors and no moon in any of them, I also had the opportunity to assess the vast differences you can get in an image from one night to the next. The best FWHM I achieved was 3.9 and the highest consistent number was around 4.9. One night that looked better than the others and yet the recorded sky brightness was a full 1% higher at 2.5%.
This hobby has so many different variables that affect the quality of the end product that can often be frustrating and yet it keeps things incredibly interesting at the same time.
Again, thank you for your kind words
Cheers
Ryan
