Description

Back to posting images after the photocalypse!

Continuing with old data and planetaries, I took these subs almost a year back.

In processing I played a lot with different kernel radii of LocalHistogramEqualization as well as the number of layers with HDRMultiscaleTransform in Pixinsight.

The colour combination is Ha(R) / Syn (G) / OIII (B), the synthetic green channel is 30% Ha, 70% OIII, enjoy!
