Description

I went on a darksite trip and wanted to shoot a dark nebula. Ended up finding this one in stellarium and I though it looked cool. I've also made a [starless version of it](https://i.imgur.com/AsUH357.jpg) which really shows all of the faint details that got picked up. Captured on September 27th and 28th, 2019 from the Deerlick Astronomy Village, a Bortle 3 zone.
