Description

A: Is normal RGB

B: I O-III and H-Alpha narrown Band

C: I A and B combined via layers in Photoshop.

With my urban seeing I am not going to get much better resolution than this with a much longer focal length scope.

The PixInsight processing used different wavelets for HA and O-III.

No 3D LUT used.
