Description

Since there was almost a full Moon I tried to image M1, which was far from the Moon and is fairly bright. I also ran a test of PixInsight SubFrameSelector effectiveness with the results. I use PixInsight SubFrameSelector and routinely remove subs with FWHM or Eccentricity outside the normal bound.  I thought that the result would be sharper image. Turns out if you take a lot of subs, you do not have to worry too much about subs with less than stellar FWHM or Eccentricity.
