Description

M81, Bode's Galaxy, is a galaxy in Ursa Major.

Processed in Pixinsight with Normalize Scale Gradient, then integrated. RGB masters combined, run through PCC. RGB and Lum initial stretch using Histogram Transformation, LRGB combined, then Masked Stretch to continue nonlinearly. SCNR (green), followed by two curve stretches to reduce shadows/increase highlights, followed by another Curve stretch to increase saturation.

This is my first LRGB image. I'm reasonably happy with it, though various approaches to processing - including the final image - seem to cause the Ha regions in M81 to underwhelm.
