M21
By Wade Corbei
This is an Open Cluster found in Sagittarius that contains a lot of stars of varying magnitudes, and lies close to M20 (Trifid Nebula). According to my notes, this OC was completed over the course of two evenings due in part to its location in the sky. It slipped behind some trees to my south on the first night, so I had to finish the sketch the following evening. Total sketching time at the EP was, I believe, approximately 1.5 hours.
A nice OC that fills up the entire FOV in a low-power EP.
Wade,
The arc of bright stars and the mixture of faint and bright star makes for a stunning, realistic view of this beautiful OC.
