Meesier 20 RGBHA

This is my version of the M20 trifid nebula from the Messier catalogue, I made this image in RGB in Munhoz Brasil, without the primary version, then I thought it would be better to add frames in HA so that the details would be more noticeable even though it was made with an SCT telescope with little contrast.
