New year, new reprocess of my M51 data from 2021!
My take last year left something to be desired. The photometric color calibration did not usually work well for me, so this year I wanted to give it another try with the spectrophotometric color calibration, in addition to the improved Xterminator tools and my better stretching skills. I went a little over the top with the saturation, because why not? M51 is full of dust lanes, HII regions, and spiral arms full of young, hot stars.
