About this image

SHO composition. Some dirt on OIII filter affected image. Rather high background sky brightness caused some problems. Outside temperature close to 30C even at local midnight didn't help either. Finally would have been better to have a shorter focal length telescope or bigger sensor to capture the entire nebula. Anyway here is the result. Images calibrated, stacked and processed in Affinity Photo.
