Description

I used the old RGB from my DSLR and Canon T3i from a year and a half ago, and the more recent data I was able to get on M42 with my QHY183M and Ha filter. Since the data was so old I don't remember all the processing steps, but I combined the old RGB data with Ha data using LRGB combination and messed with the curves and saturation.

Here is the processing steps for the Ha data:

•Stacking by LVA (10s and 180s separate)

•DBE

•EZ Noise Reduction

•Histogram Transformation

•Deconvolution

•HDR Combination (10s and 180s)

•HDR Multiscale Transform (Small Scale 5 (3), 6 Layers)

Curves Transformation for contrast
