Heres an image from a few nights ago (8th) of a section of the Veil nebula. exposures were not as long as I would have liked due to cloud passing over, conditions were very average. This is a bi-colour image taken through the skywatcher mak Newtonian scope, an Atik 314L plus mono, with a 7 nm h-alpha filter, and an OIII filter. the h-alpha filter was 10 x 5 mins exposures, and the OIII filter was 9 x 5 mins.
