What we think is marvelous about this shot is the super-faint wispy material in the outer background on the right, and also the contrasting open cluster top left.

Perhaps the Trifid itself is a little over-smoothed and over-contrasty, but still a very fine image.

Hi Martin

Have a look at Marco's technique for blending Ha, it's fantastic
