Hi Matthew,
On the SQ failures it looks like ASTAP somehow missed the calibration files. The images that were successful have "DF" (Dark/Flat) in the Calibration column. Without the calibration the process will always fail.
As I pointed out elsewhere, only exposures with your LUM filter can give accurate SQ readings. BUT you may still be able to use the results for the others to determine good or poor SQ. It's only an untested idea, but it may work & be useful for you.
Now, your RGB filters will give you incorrect SQ readings overall, but the error should be consistent across all exposures using each filter. So while they can't give you an accurate SQ reading, it may work using them for a comparison across exposures for that particular filter. So by comparing only the exposures taken with one filter you should be able to determine good to bad SQ for that filter.
So try comparing just the reds against the other reds, blues against blues & greens against greens. The actual SQ figure will be wrong, but I think it should be consistently "wrong" across all exposures with the same filter, giving you a way to compare them.
It may not work, but just throwing it out there for you to try if you wish.
Cheers,
Mark
