Description

Abell 28 planetary nebula is very faint object in Ursa Major and you cand find many images of this object. I took 10,5 hour of data with h-alfa filter, i tried also OIII and luminance, but they were absolute zero information.
First image is single 8min light, second inverted is more stretched 79x8min and final is 79x8min vesion. You can nsee from inverted vesion some faint structures at 5 o clock and 1 o clock
