Rupes Recta and Rima Birt (yet again)

Shot on 08/09/20 (approx. 1:34 am local time) with the C11, the QHY462C and presumably the TV 2x barlow.  20 day old moon.

 

Best 3,939 frames (30%) out of 13,131 frames captured.  Stacked in Autostakkert, wavelets in Registax, then cropped and enhanced in Photoshop.

Finally figured out the Quality Estimator numbers in Autostakkert.  It's crucial in terms of how the program rates the frames in your video.  If you set the Quality Estimator at a low value, ie "3", but your video is shot in horrible conditions, then Autostakkert will only look at small scale detail and it WILL confuse noise with actual detail.   That means that it will rate some awful frames highly and when you select some percentage to stack, those awful frames will get added.  When you set the Quality Estimator at a high number, ie "7" or "8", then it looks at larger areas to make a judgement as to the quality.  The higher setting for Quality Estimator works well with -- surprise -- mediocre to bad data.  But having a high setting will be inappropriate for good video since it will not really make a distinction between excellent and average frames.  

So, this all comes into play when thinking about stacking RGB.   For red and green channel stacking, you could use some intermediate value if the data is average.   But the blue channel is often crappy so you would need to adjust the Quality Estimator value for blue channel so the program can properly rate the quality of the frames.

Still grinding away on planetary data.....
