The Beehive Cluster. Naked eye limiting magnitude is better than 5.5m. The cluster is visible to the naked eye as faint round misty patch, easily missed if you didn’t know it was there. In the 50mm finder scope it shows as a sparse, round cluster of maybe 30 stars. The view through the main instrument is hopeless because the cluster spans twice the 50 arcmin field of view. It is impossible to see it as a whole. It is not a dense cluster and there is a lot of space between the stars.
