Description

First full SHO palette Hubble color processing.
I take time it was normal to have so much green when combining channel!
I take very long time to learn SHO processing.
After first processing, I compare mine to Hubble to check if colors are good and to verify if little information was true or artefact with the deconvolution.
Because I was "pretty much" similar to the Hubble picture, I restart to 0 for double the resolution with drizzle x2. Now I will always used it, even if I'm 1 arc/sec by default, it add more fine details.
On the brightest star, you can see aigrettes are not in the same orientation, that's because almost one year first capture I change the camera orientation.
