Description

Messier 67 (also known as M67 or NGC 2682) is an open cluster in the constellation of Cancer. It was discovered by Johann Gottfried Koehler in 1779. Age estimates for the cluster range between 3.2 and 5 billion years. Distance estimates are likewise varied and typically range between 800–900 pc.

M67 is not the oldest known open cluster, but Galactic clusters known to be older are few, and none of those is closer than M67. It is an important laboratory for studying stellar evolution, since the cluster is well populated, has negligible amounts of dust obscuration, and all its stars are at the same distance and age, except for approximately 30 anomalous blue stragglers. These blue stragglers are generally the results of mass transfer in binaries or stellar collisions.

Meant to be a colour image but seem Starlink decided to visit while G subs being taken. So have to see if need to redo or if can mitigate. So this Luminance only 4 x 300 seconds. I see image Rudi do which give me idea to give this a try.
