March Observer’s Challenge Report:  Open cluster M67 in Cancer. 

MARCH 2017 OBSERVERS CHALLENGE – M-067 2

Telescope: 6-inch f/6 reflector
Eyepiece: 11mm 82º AF
Sketch Magnification: 83x – FOV: 1.0º

The brightest star of the cluster on the NE tip appears yellow. The cluster is very bright and large, consisting of two sections, the sparse eastern section, and the more concentrated western part. I could count ~ 30 to 40 total stars, with many faint stars being in the background, causing a hazy appearance in these areas. A lane separates the east from the west, traveling north to south, or the entire length of the cluster. With careful and patient observing, several dark lanes were noted.

An almost perfect circle, devoid of stars is obvious in the most concentrated area on the western side.
