First successful attempt at using different focal ratios. Not bad!
Using subs from 200mm f/5 newtonian and 2 different sessions with the RC8.
200mm f/5 newtonian 10x180s 4x240s, darks, flats, ISO 800 2008-08-19
200mm f/8 RC 2×240, darks, flats ISO 1600 2012-09-16
200mm f/8 RC 10×180, 20×240, darks, ISO 1600 2014-08-26
And this is what the stack looked like:
