Here's my first light with this camera. I was floored by the results. I started this project with my QHY16200A, and later compared the same optics/exposure w/ the ASI6200MM, and it was a night and day difference. I also did a quick comparison shot of the Veil nebula with gain=0 vs. gain=100, and saw a really big improvement.
