Description

Working my way through Warren Keller's "Inside Pixinsight" with this project.

A: Had some blooming problems on the brighter stars, which I managed to reduce with a starmask and MorphologicalTranformation. Still a few color artifacts. Need to add HDR data and explore noise reduction.

B: Figured out RangeSelection and played with saturation using CurvesTransformation.

C: Version B had a greenish halo around the galaxy b/c the mask wasn't constrained well. Used a tighter mask in C and adjusted saturation, CIE-L, and contrast with CT as in version B.
