Description

Trifid Nebula - Messier 20

First processing attempt, so much yet to learn!

The image was captured in a superb dark sky site 100km from Brasilia, Brazil. Maybe I will come back to this object in the near future with a much longer integration time in order to get a better signal-to-noise ratio.
