The Lagoon Nebula and NGC 6559

Here is one of the first images taken with my new (20 years old actually) Astro Physisc-155 mm EDF refractor. I obtained this fine telescope from my old friend Terry Dickinson, who thought it would get more use under our dark AZ skies. This mosaic of M-8 (the Lagoon nebula) and the adjacent NGC-6559 complex consists of 6 x 3 minute exposures at f/7 and ISO 3200 with a Canon 6D and IDAS LPS-v4 filter.

"The Lagoon Nebula (catalogued as Messier 8 or M8, NGC 6523, Sharpless 25, RCW 146, and Gum 72) is a giant interstellar cloud in the constellation Sagittarius. It is classified as an emission nebula and as an H II region.
The Lagoon Nebula was discovered by Giovanni Hodierna before 1654 and is one of only two star-forming nebulae faintly visible to the naked eye from mid-northern latitudes. Seen with binoculars, it appears as a distinct oval cloudlike patch with a definite core."
