Description

The data was in a pretty bad shape with really bad spherical aberrations, as I used an OAG that definitely need some more tweaking.
I had three attempts at preprocessing and it was the use of automatic(!) background extraction and gradient correction that I finally got a clear picture (Abe+Abe+Gc).
I also used a completely new workflow to bring out contrast and true colours. I think it's pretty good results with such short integration time (and the messy raw data).
