M 83 The Southern Pinwheel Galaxy LRGB
Hopefully, the 3rd time's a charm! I was playing around with some of Adam Block's processing techniques (NormalizedScaleGradient, MaskedStretch, Mure Denoise, and Screen Blend), cause I'm terrible at processing galaxies and his tutorials are so informative, so I redid this from scratch. This is 10.5 hours of One-Click Observations in LRGB, processed with Pixinsight.
Hope ya like it!
