The Trifid Nebula (Messier 20) located in Sagittarius.

Its name means 'divided into three lobes'. The object is an unusual combination of an open cluster of stars; an emission nebula (the lower, red portion), a reflection nebula (the upper, blue portion) and a dark nebula (dust clouds that absorb and block light from the bright objects behind them, causing the trifurcated appearance).

The Trifid Nebula is a star-forming region in the Scutum spiral arm of the Milky Way. The most massive star that has formed in this region is HD 164492A, an O7.5III star with a mass more than 20 times the mass of the Sun. This star is surrounded by a cluster of approximately 3100 young stars.

And on a personal note, I am officially retiring the newt until I get a proper mount. I lost half my data over the 3 nights period and I don't think it is worth it. On a brighter note, I finally got my reducer for my 80mm, hoping the mount will be less annoying with that image scale.

Comments and feedback are, as always, much appreciated!

Clear Skies!
