M20, the "Triffid nebula"




M20, the "Triffid Nebula" in constellation Sagittarius. Distance about 7600 light years.

Actually this is my firs image of a reflection nebula from a dark location, what a difference!
Image above is only Ten minutes exposure (Luminance channel)
Ten minutes was all I could do due the speeding clouds, I'll continue with this later.
I couldn't believe, that anything can be done from so thin data but here we go, nothing beats great instruments and a dark location!
Ones again, this is a preview image, since I don't have yet all the calibration filesa nd the exposure time is a way too short.

Details:




Camera, Apogee U9000
Exposures, 2x300s for the Luminance and 1x300s for each RGB channel.
Darks, NO Flats
