Description

On two nights, just after my principal target moved out of view I pointed my scope towards this nice nebula to give a try.
In the end, I am happy with this result considering that I didn't spend a lot of time on it.

The color composition was made using Ha on R, O3 on B, and 50% of O3 in G.
