NGC 7024. Even though RNGC claims non-existence for this cluster, it is a very nice object of about 30 stars close to the NGC position. The diameter on the DSS is about 8' x 8', and the brightest stars are around 11th magnitude, not far off JH's estimate of 10.

Discovered in 1786 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "a cluster of coarsely scattered pS stars of several sizes, not rich."
The SAC database comments: "HURST: 10in, faint cluster around 10m star, 10'd 14*"
The RNGC (Sulentic and Tifft 1973) notes that this is a nonexistent object. Their coded description reads NOCL S.
