The Trifid Nebula Revisited

M 20, LRGB

July 6th, 2018

The Trifid nebula is one of my all time favorites. It’s bright, it’s in the heart of the milky way, and its diverse and colorful. It is also surrounded by nice dark and reflection nebulae and is accompanied by its own little open cluster, M 21. I have shot this object many times before but this time I wanted to really knock it out of the park, so this was shot at a bortle 5 site rather than my home (a bortle 9) and during a new moon. I’m pretty happy with the way it turned out and I think my star colors are pretty decent here.
