Corwin's Notes

===== NGC 7082. This cluster was found by WH in October of 1788, and observed again by JH (who gives no sweep number). WH notes, "An extensive cluster of large stars, considerably rich, above 20' in diameter." This makes it clear that my earlier estimated size, 11': x 9':, is too small and does not include all of WH's cluster. JH's description is appropriate; he notes, "A * 10 m, the chief of a p rich, L, coarse cluster. Stars 10 .... 13 m." His position, however, lands in an empty space about a minute of time east of the brightest star in WH's apparent cluster, BD +46 3329. That star is on the western edge of the cluster and could well be the one that JH measured. But without a sweep number, it will be difficult to dig out of his observations. In any event, I've adjusted my previous position and size to more or less follow WH's comments, if not his position. I put the center nearly half a minute of time west of his.

Steve's Notes

===== NGC 7082 17.5" (9/7/91): fairly bright, large, 15' diameter, scattered, no distinct borders, situated in a very rich field. Two mag 8.5 star are on the west side, a mag 9 star is on the north side and also a mag 9 star is off the east edge. Not impressive and except for five or six brighter stars mag 8.5-9.5 at the edges this cluster would just be a weak field enhancement in the Milky Way.
