This image of the M52 area was taken at 135mm focal length during massive skyglow due to nearby city and moon. Values were taken to the extremes during post processing to bring out the stars. I am not sure if the denser part is showing nebulosity or the lens vignetting due to the extreme values.

After the plate solving, I need to work on my aim some more
