Description

Abell 28 (PK 158+37.1) is a 13.5 mag planetary nebula in the constellation Ursa Major with very low surface brightness and a diameter of about 5.5 arcmin. The brightness seems to be uneven distributed over the disk. The PN has a rather bright rim in the SE, while it is getting dimmer to the NW. The blue central star ( 17.4 mag) is out of the center.  (Wikipedia)

There are few images of this target and now I know why.  This one is very difficult!  I can't remember spending so much time trying to coax an image.  More imaging time is required.  Perhaps someday...
