Description

This is my second attempt at narrowband imaging and was a bit of a challenge. For this project I gathered just under 23 hours worth of imaging data over 8 nights. Processing such a vast area with so much happening created a unique challenge. I still probably went a bit overboard with saturation, but I think it turned out pretty good.

Any and all criticism is welcome.

Lights - Just under 23 hours integration time under bottle 5 skies in Nova Scotia, Canada. Dropped the worst of the worst (unusable) frames, about 3-4. About 20 frames were also rejected during registration because my scope went out of focus.
