Description

First light with my new Stellarvue SVX102T-R and Orion Atlas Pro. I choose something relatively easy to start out with making sure everything was going well.

Messier 44 or M44 (also designated NGC 2632) is an open cluster in the constellation Cancer. It has an apparent visual magnitude of 3.7 and its angular diameter is 95 arc-minutes. M44 lies at an estimated distance of 577 light years.

M44, the Beehive or Praesepe Cluster is a large, naked eye star cluster known since antiquity. It is one of the closest open clusters and may have formed in the same interstellar cloud with the Hyades Cluster. According to Kharchenko et al. (2005), the distance of M44 is 610 light years and its diameter is 15 light years. It contains 1000 stars and its estimated age is 500-700 million years.
