Messier 20 - The Trifid Nebula
A combination reflection and emission nebula near the constellation Sagittarius. Imaged from Stooges Field, this image is composed of 12 - 5 minute subframes without filters through a Celestron 8" SCT at f/10. Unmodded Canon DSLR, 4 darks, no flats or bias. CGEM mount guided with PHD.
The three lobes of this nebula usually appear with a stronger pink color. The prominant blue in this image may be the reuslt of the unmodded DSLR, which tends to be less sensitive to redlight.
