Description

My first bi-color. I am not very happy with it. I had to corp a lot because of an alignment issue.

The Oiii data seemed really noisy. Maybe I should have waited for new moon.

There is some halos around the stars. I think that came from a curves saturation stretch done to the stars with a star mask.

A- First attempt

B- Re-saturated the stars with a better starmask to fix halos.

C- I tried some stuff suggested by Goofi, rflinn68, and Jon Rista and then I went way down the rabbit hole playing with colors. I love the artistic freedom mono imaging gives you!
