Rosette Nebula - Ha Mono

[Buzzard75]

I normally capture Ha, SII, and OIII when doing narrowband, but my window on the Rosette is closing. I've wanted to capture it all winter, but the weather and other priorities have gotten in the way. Now I only get a couple hours on it before it's gone behind a tree or too low on the horizon. So, I chose to focus on one filter. This is the first mono image I've published as a 'finished' work.

Captured 04/03/2020 with the 77% moon high overhead.
