The Veil Nebula is the remnant of a supernova from about ten to twenty thousand years. Early humans probably witnessed it, but this is a bit before written records so alas we have no accounts of this event.
I spent 2.3 hours on this target at f/4.0. In hindsight I probably could have spent some more time on it, but there are a lot of interesting targets in the summer!
You can see both the Eastern (left) and Western (right) portions of the Veil Nebula on either side of the image, and you can make out some of Pickering’s triangle in between. Maybe in a future summer I’ll revisit this one!
