M41 NGC 2287

Object Type Open Cluster
Constellation Canis Major
Magnitude 4.5
Size 39.0' x 39.0'

Just 4 degrees south of the brightest star in the sky, Sirius, is a very beautiful open cluster, M41. Under good skies it is visible to the naked eye. Most of the brightest stars are blue main sequence stars, however there is one orange giant star near the centre of the cluster.

M41 is a fine object for binoculars and is compact enough to provide an excelent view in a low magnification telescope.
