Description

I've made this composite image by using data from broadband and narrowband light pollution filters. Previously, I've uploaded a version with only data from L-pro filter which was very noisy because I had to stretch the curve pretty far out to get any detail. Now adding the UHC data I can get detail without getting too much noise.

Still it is pretty hard to image in an extremely light polluted area...
