M20 = NGC6514 ( 18h 02.6m -2302, 8.5 mag. )

Trifid Nebula in Sagittarius was discovered by LeGentil in 1747 and Messier observed it on June 5, 1764. Nebula's name was suggested by William Herschel who noticed dark bands crossing emmision part of the nebula (reflection area is more difficult visually). M20 is located about 130' NNW of Lagoon Nabula (M8 - see finder chart below).

The above image was taken on July 14, 1999 from Sooke, BC. Cookbook 245 LDC CCD camera was used on Ultima 8 f3.0 telescope autoguided with Cookbook 211 LDC CCD camera on a piggybacked 500mm f8 telephoto lens. It is composed of white exposures (11 x 120 sec.) as well as cyan, magenta and yellow-integrations (5 x 120 sec. each) were combined in AIP4WIN. Resulting color image was then adjusted in Lab color space with Corel PhotoPaint 8.
