Notes: This is one of my QAD (Quick And Dirty) shots, imaging from my backyard in the city. I ran into problems with the set taken this night with large dust blobs that didn’t remove with the flats taken. This forced heavy cropping of the image to get this QAD result. Processed in PixInsight with BlurXT and NoiseXT.
