The Trifid Nebula (Messier object 20 and NGC 6514) is located in the constellation Sagittarius. According to Wikipedia, 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) and a dark nebula (the apparent 'gaps' within the emission nebula that cause the trifid appearance.) Image consists of data captured on the evenings of July 21, 24 & 25 and added that captured on Sept 3, 2013 from Top of Mississippi Skies (T.O.M.S.) Observatory (lat 34.987°N, lon 88.276°W.) with a TMB-130SS Apochromatic Refractor, mounted on a Celestron CGE-Pro mount; AutoGuiding was with a Lodestar camera via PHD2; an SBIG STF-8300 OSC camera was used with an Astronomik CLS CCD Filter; auto-focusing was with a MicroTouch focuser controlled by Rigel Systems nSTEP and ImagesPlus Camera Control (IPCC) . The final image is the result of a total of over 5 hrs of data acquired using IPCC. Final processing was with IP v5.75.
