Description: I like this wide field version better. I've also applied my latest processing workflow. Galaxy arms are still not in the classic blue which I see from others all the time but I can't get that without all the colours looking unnatural. Maybe someone can help me with that.

Description: Trying to compensate, what I believe is an issue with ZWO RGB filters, the blue lack using some blue enhancement curves only on the galaxies.
