Thanks for the confirmation. FYI, I got NSG to work and it produced an exceptional result. Thanks!

I find FWHM to be useful to determine whether I should keep shooting, and for culling out frames with wind gusts or cable snags or just passing bad seeing conditions. So to re-state that thought, FWHM may not be the best way to weight frames, but i…

So I think, (?), I've answered part of my question, which is that , yes, the subs must be star aligned/registered. This is not intuitive in some ways because other weighting occurs before registration. Also, the fact that the script does photometry/…

And as a side note, there seems like there may be a bias, (lowercase "b", not the calibration frame), amongst those who can afford fancy CCD cameras against the idiosyncrasies of some of the newer affordable CMOS cameras. When I go through the tuto…

But there is no issue with using Flat Darks instead of Bias to calibrate Flats, right? I takes ~5 minutes extra to shoot Flat Darks after shooting Flats, so not a huge time savings, and I have heard (so much hearsay, but nonetheless...), that Bias …
