Description

Tracking was poor with this session.  Even with just 5sec subs, many fainter stars have an out of focus/distorted look, even though I verified focus prior to imaging. They are those farther from the original center before cropping, so coma may have played a role as well. But maybe colimination? Probably should have started over and reset polar alignment. Another learning experience. Adjusted the color balance to try and highlight more of the nebula.
Look forward to imaging this one again. Interesting the "trapezium", similar to Orion's  in the core.
