Great Success with SGP - M31

I, like most amatuer astronomers, have many images of M31. They suffer from two problems. First, with my scope and camera, I always cut the ends off the galaxy. Second, the brightness of the galaxy makes the hydrogen regions impossible to see. SGP to the rescue.

I have just completes two mosaics, one in H-Alpha (18 hrs.) and one in OSC (15 hrs.) I then used PixInsight's NBRGB_Combination tool to combine the two mosaics.

I have really pushed the H-Alpha in this image. Because of the image size, you will need to access it on my Dropbox site.

SGP worked flawlessly including many meridian flips.
