A Dense But Open Cluster In Monocerus

M-50 of Monoceros

This rarely mentioned Messier object looks like a diffuse, large spot even through the finderscope. On a low/moderate magnification a view of solid, dense open cluster appears in front of our eyes. A very nice member of the cluster can be found around 9′ north from the middle of the cluster: a red giant of a color-index of 1.7, catalogued as HD 52938. With its 7.82 magnitude luminosity its also the brightest star of the cluster. Interestingly, because of its shiny red color, I wouldn’t think that this star is nearly 2 magnitudes brighter than the other stars in the centre of the cluster, which look like they’re the brightest by far.

  1. Fernec, I enjoyed your work, I too like to sketch open clusters at low power. I shall be following you into Monoceros very soon.

    Congratulations, Dale
