Large!, bright, rich, no notable central condensation, a roughly triangular shaped cluster 60' in extent, fills the low power field (1° @ 60x) of the 18" 'scope, hundreds of members evenly matched in magnitude spread equally across the region

Group at XVIIIh34m N. 5°16'. Very large, subdivided, chiefly 9 and 10mg.

Also in desc. for NGC6633...
Between it [NGC6633] and θ Ser, nearer the former, is a beautiful large cloud of stars, chiefly 8 and 9 mg., a nearer part apparently of the Galaxy; visible to the naked eye, and requiring a large field.
