Another success with my UHC filter, the Bubble nebula turned out terrific! It wasn’t too bad to find, but as soon as I landed on it, I knew it was it. The distinct circular shape came through perfectly, and there was so much more present in the stacked image that I would have imagined. This is 53 images of 20 seconds each, 1600 ISO.
UPDATE: I tried experimenting with the image a bit by stretching the three color channels separately. I also did the background extraction on the individual channels. Although it doesn’t look as good to me since I am quite fond of deep red, I do think it brings more character out.
