M13 at zenith
« on: June 07, 2017, 06:26:55 PM »
tried to post once:

need help with color still.  white star tests not giving my confidence.  Does anyone know the correct starting point for exposure ratios on the Atik One 9.0?  I am getting very strong red, weaker green, and doubly week blue.  I'm going with 1/1.3/2.0 currently after recent testing.   This photo is result of 20 subs on 8"Edge at f10.  Sound good or bad to anyone?
