Open Clusters (OC)

[glenc]

These are the 50 brightest Open Clusters in order.
They range from magnitude 1.6 to 5.7.
Only M, NGC and IC objects are listed.
Some interesting nearby objects have also been included.
To pick the best OCs look at them with a telescope or use software that shows stars to mag 14+

* are my favourites.
