Cloudy night, having a break in processing another data set, this thread sparked interest as to the gains of Astrometric alignment versus "auto - star matching" or "manual - two stars". Test after test I measured the FWHM of subs that had been aligned/combined using the three algorithms. I could not tell the different from statistical figures between the alignment methods. This leads me to the conclusion that Astrometic alignment has no gain over regular pattern matching or manual 2 star matching. What it may assist with is the addressing the initial rotation or flipping of subs, alas this can easily be addressed with a manual 2 star alignment. The point being is while its probably pretty cool to platesolve and align an image, you're actually getting no better result performing the alignment task any other way. They'll all rotate, skew, shift to deliver the same end result in alignment.
You may wish to perform your own tests to validate and perhaps use another alignment method if you're still having concerns in getting the corrected GSC operational.
