Re: (IAAC) Obj: M57 - Inst: 6 newton,f/8 ,dobsonian mount
I was looking about an hour on it, and i saw something. Maybe my brain think there was something, for that reason i put there (?) . My friend ,
owner of the telecope saw this too. I'm on the vacation, I live in Europe. The sky was unusually clear, you vere able to see NGC 7000 with
naked eye. Only on the horizon was some lights from the city. I know, the central star is about 14.5m ; but universe is full of unknown. You can
use the formula m min ~ 2.5 + 5 logD, and from that you know , limiting magnitude for 6" newtonian is 13.4 .I only reported what i saw.
