Description

After my recent experience with dark nebulae I looked for brighter targets and went for the Andromeda Galaxy. Kind of overcompensating? Maybe... Anyway, the problem is that M 31 doesn't fit the FOV of my setup. Fortunately an uncommonly long stretch of clear nights came across so the time had come to try a mosaic.

You see a mosaic of three upright panels. I could elaborate for hours on going back and forth between ASTAP (stacking), StarTools (cropping away artefacts and gradient removal), ASTAP (stitching) and StarTools again (post-processing). Or cry about my poor notebook making me bin and reduce the resolution to 60% because otherwise the PC just surrendered...

But I'd rather have a look at the stunning Andromeda Galaxy :-)
