Wasn't very happy with the data I got on the weekend but I figured I'd still try to get something out of it. The Lum subs were super noisy, I suppose cause they're not long enough? Also the camera has a very obvious gradient from top to bottom and blue channel was captured after meridian flip so it created a terrible rainbow kind of effect when the rgb channels were combined.

After your write-up I was expecting the worst, but not so. Not too bad for an 8" scope and 1 minute subs! The longer you can go the better, of course.

Not too bad at all Tim. It may have less to do with your sub exposure time but more your overall amount of exposure time. 50 minutes of luminance isn't a lot in the grand scheme of things. Put another night purely for luminance and it will help a lot with the noise.
