Category: Open cluster.
Constellation: Vul
Data: mag   size 
Position: RA :  DEC :
With a 38mm Giant Erfle eyepiece the 6" f/6 gives about 25X and a nearly
two degree field of view.  At that power Stock 1 is large, bright, little
compressed and pretty rich.  I counted 28 stars resolved and the cluster
is about one third the field of view.  Moving to a 22mm Panoptic resolved
59 stars with several nice pairs and a chain of 8th and 9th mag stars
in the center, it appears on Uraonometria.  Even with the 10X 50 binoculars
there are 10 stars resolved and appears very much like a cluster, a 
bright fuzzy spot in the Milky Way.
