Hi George,
Ok
firstly, stop the bragging about the clear weather ok, we southerners are currently severely depressed during winter, hearing your wonton gloating just makes us more depressed
Seriously though, this is a good effort and I think the colours are indeed pretty close to what they should be. You see, many image processors work the nebula to be very Blue-Red but in reality if we are looking at the physics going on here (I co-authored an article on this with David Malin which appeared in the Sept 07 edition of Sky & Space mag), the Trifid has a lot of dust and molecular cloud associated which not only contributes to the blue reflection due to Raleigh scattering but by mixing also imparts a turquoise-green hue and even white in the area just outside the central dust lanes ..and you have that showing here quite well
