NGC 55
The Whale Galaxy, officially known as NGC55.
My first image using the super pro dataset subs.
Post processing was slightly demanding, using only 3 Lum (out of 4 - one sub was rejected due to a horizontal band that I was unable to correct), 3 Red, 4 Green and 2 Blue subs, but I believe that in the end the noise was relatively controlled, and I tried to balance contrast and colour.
Processed in Pixinsight and finished in Photoshop just for a couple of colour touchs.
