Description

Sh2-200 is a planetary nebula. It is not only faint but also small for my setup. I had to do tight crop. This nebula has rather stronger  O3 signal comparing to HA, especially on the claw.  I collect my NB subs mainly with moon in the sky and save dark nights for luminance and RGB.



Subs:
Ha: 33x1800s
O3: 40x1800s
R/G/B: 30x120s each
