Description

I tried STarizona Filter Slider and cheap narrowband + HyperStar + ASI294MM,

Ha = Astromania Ha 12nm $120

OIII = Celestron OIII 93624 $110

30 subs of 180sec.

R=H, G=0.8*O + 0.2*H, B=O

Good: very fast, rich photons

Bad: ghost!

Bad: when I use Astrozap Dew shield, very hard to replace filter.
