Description

Data taken with AG 20" iDK from Skygems Observatory in Namibia. Channel combination using pixel math, since the lack of S3 and overwhelming O3, I gave S3 less weight and under-stretched O3 a bit before combination.

6 x 1200" Ha

6 x 1200" O3

5 x 1200" S2

R = 0.8 * Ha + 0.2 * S2

G = 0.2 * Ha + 0.8 * O3

B = 0.1 * Ha + 0.9 * O3

DBE and SCNR and then performed some curve and HSL transformation in PixInsight. Post in Photoshop to reduce noise and bring out more details.
