Description

This is my second attempt at the Orion nebula, the first having happened in 2015!  For whatever reason, I never got back to attempting this target until now.  After working on M31, it was late enough that this was coming over the trees, so I turned the scope back and started collecting luminance data.  It was too late for me, though, so I didn't stick it out for the color filters.

The gradients in this image are more manageable than what I found in M31, for whatever reason.  The processing was much less painful and it found the black point automatically.  It is untracked and it shows in the star shapes within the nebula where I have the best focus.  Outside of this region, it is very clear that this is not coma-corrected and that hides the tracking problems.  I'll revisit this target when my auto-guiding is working.
