The Trifid Nebula (M20)

Post by Christopher K. » July 30th, 2015, 6:13 pm

I had to use the search function on the Forum to make sure there really wasn't an entry yet. The Trifid is one of the showpiece objects in Sagittarius. I don't believe I've ever seen it through a telescope (well, perhaps once in the 20OGS). It lies about 5000 light-years away and of course it is most noted for its converging dust lanes, separating its body into three almost-equal parts.

Here's a false-color view from Spitzer...

Christian vd Berge obtain a good shot of the section sky housing both M20 and M8 (M21 is above M20). From HRPO it would probably take at least an aperture of fourteen centimeters to pick up three famous dust lanes.
