Description

Finally got to processing a full frame of the data I used for my prior Pillars and Stellar Spire projects. (-:

I started with the color using a Hubble palette on OIII, SII and Ha with green removed and Magenta stars corrected in PI.

I then overlayed a deconvolved Luminance Ha layer to help with contrast and detail.

Finally I overlayed an RGB Lighter Color layer to help restore some star color. This is very simple if you don't mind the faint magenta rings and center bright spots. Gaussian blur helps hide some of that. (-:

Final sharpening uses a PS Unsharp Mask, 100, 8, 5.

All data except RGB is 2x drizzle.

Description: Used an Ha Luminance layer rather than Soft Light. This enabled brighter colors with more detail.

C

Description: Minor cosmetic edits to improve overexposed stars and reduce color noise.

D

Description: Added 2 pixel gaussian blur to stars to help hide some RGB overlay artifacts.
