Description

Versions with differences in contrast but also in the DrizzleIntegration method options and work arounds, which left some blue and green noise pixels hidden here and there in one version posted, and left black pixels in the centers of stars in another. Pixinsight’s DrizzleIntegration’s pixel rejection, when on, left black pixels in some star centers; when off it left more noise in the channels with less data. I obtained a very clean result for L by DrizzleIntegration of a “Super Luminance” of the whole 71 subframes. For R, 23 subframes was enough to average out a good result from DI with pixel rejection enabled. For the B and R channels, 16 subframes, pixel rejection worked great except for the star centers - had to choose between a result with noise or black stars, I prefer the noise but really neither!

L = 16x 900s

R = 23x 900s

G = 16x 900s

B = 16x 900s

SuperL = 71x 900s
