Photo by Carol Santulis (MAS Member): It was a lovely night for a star-trail. EM1, 12mm/f/2.0, ISO 800, 6 sec, f/2 for 1.5 hours. It was super dewy but my new dew heater worked great at about 55 degrees F. Four meteor showers were to the east which gave me lots of entertainment.

The Trifid presents the unusual combination of an emission nebula, a reflection nebula, and a dark nebula all in one object! The Trifid lies 5,200 light years from us in the constellation Sagittarius.

Messier 21 (M21; NGC 6531) is the beautiful, small open cluster containing 57 stars that is visible to the upper left of the Trifid. M21 is 3,900 light years from us.

Photo by Laurence Mohr. The Bubble Nebula (Caldwell 11) located ca. 10,000 light years away in the constellation Cassiopeia. The affect of the hot central star on the surrounding hydrogen gas is clearly visible – causing the gas to glow like a neon sign and forming it into a bubble with its stellar wind. 36 exposures at 10 min each; ISO 800; EdgeHD 1100; f/7; taken in Brooklyn, Wisconsin.
