I started to image M51 a little while ago but only got 4 x 5 minute subs before the clouds came in – frustrated I gave up!
Its going to be a cloudy weekend here so I tried adding those 4 subs to my images of M51 taken about a year ago.
I think it has helped but I really need to get a bigger scope if Im going to get better galaxy images.
2 small spiral galaxies to the NE (if N is at the top) are IC 4263 and NGC 5169.
Also first use of drizzling technique in PixInsight to help improve resolution.
