Description

This beauty shows very painfully the blooming I always experience using the Baader OIII filter... but despair not, new APO just arrived so I'll see shortly if something changes compared to my usual newtionian.

I decided to do RGB only without L for the stars and the result is much fuzzier than my most recent works, I should probably try a synthetic luminance and compare the differences.

Meanwhile I'd like to have at least a bi-color of this nebula, as Ha is strong too and very prominent in the lower "moustache".

SII is almost non-existant also with 10-minutes subs.

Unfortunately I took Ha/SII after repositioning the camera so the diffraction spikes do not align and the end result isn't pretty at all.... next time!

I really love the shape of the small galaxy above, enjoy!
