Description

Abell 35 (Sharpless, Sh2-313) was considered to be an old planetary nebula (PN) approximately 16 x 11’ in apparent size with low surface brightness in the constellation of Hydra about 1,200 light years distant. At 5.2 Light Years across it would be one of the largest Planetary Nebulas if that was realy the nature of the beast. However, later research around the brighness of it 'Central' stars and shock waves within the Nebula,  such as around the blue 'Eye',  while it plunges through the interstellar medium, have discounted it being a PN.

I tried to improve on 10 minute exposures from last year but it really needs the full 10 minutes so I stuck with that.
