Description

It was fun to capture this galaxy in HaRGB: I was blown away with how much hydrogen alpha there is in this galaxy! Quite photogenic for sure. I had initially dedicated four nights (consecutive ones, amazingly given the weather!) to this image and noticed the very faint arms of the spirals starting to appear. So I decided to dedicate one more night to this image and am glad I did! The bunch of small galaxies just to the top of M101 (between it and NGC 5477) were also fun to see.

The first image is the full image showing NGC 5477 up at the top and the revision is a crop bringing out more of the details.
