Description

First light of the Baader Narrow Band filters!

I'm happy about the result even if I was hoping for more faint blue hue.

I don't like the blooming around the bright stars in OIII at all and need to understand why it happened or if I'm doomed to always post-process it.

Tracking wasn't that great but by now I'm used to deal with elliptical stars

False colour, mapping:

R - Ha

G - (0.1*Ha)+(0.9*OIII)

B - OIII
