Description

Owl processed in HOO

Ha: 86 x 300s Gain 200 -15c
Oiii 83 x 300s Gain 200 -15c

I took this over the course of a month while shooting other targets. Using NINA and custom horizon was been wonderful. At 196mm, I cropped this one in quite a bit since it just made sense.

I stretched it pretty hard to get the outer ring to really shine, but tried to keep the main nebula from overblowing in. I did an HDRMT with 3 passes and lightness mask to keep it under control. This really is a beautiful nebula and really enjoyed the bicolor nature of it as it is quite different from it in full RGB.
