Messier 33 - The Triangulum Galaxy
An augmented color picture of Messier 33, highlighting the hydrogen rich regions in pink. My initial goal was to create an exploratory image of the galaxy and accept the resulting raised noise floor in exchange for better overall visuals on the very faint ring-like Hydrogen emission shapes on the outer edge, especially lower and lower right regions.
The image has been exposed during four nights in October and November, per channel:
Luminance 20 x 10 minutes
Hydrogen alpha 15x20 minutes
Red, Green and Blue 11x10 minutes each
For a total exposure of 13 hrs 50 minutes.
Taken with StarlightXpress SXVR-H18 thru William Optics FLT-110, WO AFR-4, and Baader filters.
Reprocessed data with proper calibration and better workflow for more even transition in the faint Ha regions to background sky.
