Description

June is always a great month for imaging with the ocean marine layer covering the lower altitude city light. Skies at 4,200' in Julian, CA are then 21.5+ SQM nearly every day.

This is the first of three objects I acquired over 12 days. Only 4 days were overcast when the wind blew the marine layer east into and over the mountains.

"The Wild Duck Cluster (also known as Messier 11, or NGC 6705) is an open cluster of stars in the constellation Scutum (the Shield). It was discovered by Gottfried Kirch in 1681. Charles Messier included it in his catalogue of diffuse objects in 1764. Its popular name derives from the brighter stars forming a triangle which could resemble a flying flock of ducks (or, from other angles, one swimming duck). The cluster is located just to the east of the Scutum Star Cloud midpoint.

The Wild Duck Cluster is one of the richest and most compact of the known open clusters. It is one of the most massive open clusters known, and it has been extensively studied. Its age has been estimated to about 316 million years."
