Description

Was surprised to see this target after wrapping up another...So went after it with clear skies and high in the sky for the majority of time of imaging. Imaging at about 52 mm from flattener when should be at 55mm. I wonder if that is the reason for outward streaking as distance increases from center. Need to learn how to properly collect and apply flats to help with the gradient challenges. Combined RGB, then average merged Ha and Lum, then added to RGB for final frame. Tried to avoid over processing and as always sought star color. Might consider 1x binning for RGB...noticed that when converting to LRGB in AA, the effect of a processed Lum over less processed RGB's was not as good as with the 8" SCT. Guided with new QHY 30 mm guide scope and took a while tightening everything down to get rid of the rice streaks that were supposed to be stars. Overall happy with last minute decision and not a lot of subs compared to what should probably be a much higher number.
