I am new to PixInsight and took RBGL data set of M31. Used the best Lum image as a reference and about 50% of the Lum images registered, 25% of the blue, and none of the green or red. I used the default settings to start and then adjusted parameters in "star detection" and "star matching" with no improvement. Then I used the best red image and tried SA and the only image it would align to was itself - WTF
I can align the images by hand on a light table but the program cannot do the job??
