Description

First approximation of narrow band image. Will keep collecting images.

Second image uploaded with an addition 5h of O-iii data.

Third image uploaded with 3h of 3600s H-alpha data instead of 11h of 1800s data.

R = H-alpha

G = 0.5 H-alpha + 0.5 O-iii

B = O-iii

Plan to collect more H-alpha and see if red comes out more, if not will be finished tonight.

Processing:

Linear Fit H-alpha to O-iii

PixMath to integrate to RGB

HT stretch to STF parameters then Deconvolute

ACDNR with Mask and final stretch
