Stock 2 (St 2) - Muscle Man

Introduction | Map | Own Observations | References

On this page I collect my observations of the open star cluster St 2 (Muscle Man) in the constellation Cassiopeia.



The open star cluster St 2 in the constellation Cassiopeia got its name Muscle Man due to its characteristic shape and is, according to Stoyan, a "must" for small telescopes. Using small magnifications or binoculars, it can be observed together with the Perseus double cluster, which makes the most pleasure, as Stoyan points out. Using binoculars, I had, however, difficulties in finding the "Muscle Man" at all... But I did find it with the PS 72/432 refractor.

St 2 between Cassiopeia and Perseus (this open star cluster belongs to Cassiopeia) and Perseus Double Cluster NGC 884/869

Detail map: Perseus double cluster NGC 884/869 and Mucscle Man St 2; above the double cluster, there is a kind of oval (arrows), which helps me identify the double cluster and find the Muscle Man St 2
