M51 (reprocessed)

A reprocess of the data captured in Feb/March 2016 (my original attempt is also in this album). This is an LRGB image with about 6 hours integration time. The main difference between this and the earlier image is that I concentrated on correcting the starfield colours and sharpening the galaxy.

Wow nice result and good thing you picked this back up. So much better than your other one (which was already something that I can only hope to once achieve). Top right galaxy (IGC 4263 I think it is) also got so much better!

Pieter - thanks !

In addition to the Photoshop's High Pass Filter and Unsharp Mask, this time I applied Pixinsight's HDRMT routine, which is excellent at sharpening images.
