I learned a lot this time around. Blue-Red channel trickery to kill the green weenie. Color halo reduction. All kinds mask selection/load/subtract-ery. Good stuff - and absolutely no way to reproduce how I got to the endpoint. However ... I am repeating to myself ... be satisfied.
At 200mm the image scale for M33 isn't all that great. At least compared to M32. It's smaller than I remembered :). I was also a bit surprised that 60 min didn't pull out more. A late rising moon just below Kitchen Mesa accounts for the still persistent gradient in the lower right corner. The presentation could be improved but dear reader ... there simply ain't no mo' photons. I give you all I have.
You know what? I'm satisfied. Mostly :) Hanging up the hair-shirt for a bit before I tackle another set of data from the New Mexico trip. Click for larger image.
