I know this is a repost of an earlier image, but I thought it would be interesting to be able to compare two compare two processing methods, I welcome all comments and suggestions on how to improve my image processing. I've been learning to use Pixinsight, I reprocessed my M57 from last year I rejected more bad data reducing the luminescence to 18 Hours 50 Minutes, RGB 2h 25m per channel.

There is much more detail in the Ring, with the outer older portion of the Ring more easily identifiable. I'm also happier with the colour balance

The image shows the outer shell of M57, NGC 1296 and also CGMW 5-08786 and 2MASX J18530959+3305385.
