This was purely a test ignore image quality this was low down with cloud roiling over, it is just a test to see how the software with a 70mm refractor can generate a mosaic of four panels of M31 you can see the potential for the framing of such objects, although in RGB you need to do a colour for each panel .

The panels where treated with fits liberator and using blend layers in photo shop which didn't align them but just blended then, for each panel I selected difference for the blending mode in photoshop to nudge the panels into alignment then put back to normal then blen layers.
