Title: Propeller Nebula Simeis 57
Post by: Carole on Jun 17, 2021, 23:07:33
Was planning on getting another night on this (albeit nights are short ATM).  This was supposed to be a practice process, but since the skies aren't going to clear for at least a week and then it will be full Moon, decided to post up as is.  This is the first time I have imaged this target (one of the few I haven't done previously).

Taken over 2 nights just before summer solstice so very little darkness from Home.
Atik460EX, Skywatcher Esprit100 + Fr x0.79

Oiii 11 x 300secs binned (55mins)
Sii 11 x 300secs binned (55mins)
Total imaging time 4 hours 50mins
