Following last night's Pixinsight Zoom meeting I've repossessed an image of the Andromeda Galaxy, originally taken using my SX694, Altair Starwave 70EDT and Cem60 mount.
18x180s luminance, 6x180s R,G and B and 6x600s Ha subs.
In the session last night part of it was using a continuum subtraction script to isolate the Ha portions of the Ha image. Once prepared, the image with just the pure Ha was combined with the red channel of the RGB image whilst in the linear mode.
The image was then processed using StarX, NoiseX and combining the luminance channel later on. Stars were then replaced to finish and levels and curves adjusted.
