Corwin's Notes

===== NGC 6828 may be simply a random scattering of stars around HD 187567 = SAO 125116, but has the look of a scattered cluster matching WH's description: "A cluster of coarsely scattered stars, with one pretty bright star in the middle". JH was pretty dismissive of the cluster, calling it on 21 August 1827, "Coarse, straggling, 15', not remarkable; chief * = 9.10 m", and on the next night, "A * 8 m in a poor cl, hardly to be called a cluster. (Night very bad)." He gave a full position on the second night, listing only an estimated NPD on the first. The GSC has a scattered concentration of about 60 stars, 12 x 10 arcminutes across, centered about 2.5 arcminutes southwest of the star, but this does not show well on the POSS1 prints. It does, however, show up on the DSS2R image, where it extends to about 15 x 10 arcminutes. I've adopted this somewhat larger size and the position southwest of the star for the cluster.

Steve's Notes

===== NGC 6828 17.5" (8/25/95): group of stars about 8' diameter surrounding mag 6.5 SAO 125116 in a rich star field. A mag 9 star (SAO 125117) lies 2.0' S and a mag 8 star (SAO 125109) is 4.7' SW. Besides these bright stars there is 6' incomplete ring of approximately 50 stars mag 12-14.5 roughly centered on the mag 6.5 star. The majority of these stars are located in the northern half of the ring.
