M44 Beehive Cluster

Messier 44, sometimes called Beehive cluster, is visually one of the biggest open cluster, which can be observed from northern hemisphere. Previous picture, taken 3 year ago, was done with focal length 1000 mm. Now I changed the strategy and used only 630 mm. I think this was a good idea and whole cluster is perfectly framed.
