NGC 6828 may be simply a random scattering of stars around SAO 125116 (I've adopted this star's position for the "cluster"). The GSC has a scattered concentration of about 60 stars, 12 x 10 arcmin across, centered about 2.5 arcmin southwest of the SAO star, but this does not show well on the POSS1. Perhaps it would be more outstanding visually.
Synonyms: H VIII-073
Discovered in 1788 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "a cluster of coarsely scattered stars with one pB stars in the middle."
The RNGC (Sulentic and Tifft 1973) notes that this is a nonexistent object. Their coded description reads NO CL DC.
16-inch f/10 SCT (127x 290x)
It could well be just a busy star field. But the area show faint stars in strings more or less concentrated around a magnitude 6.4 star. Seeing in low power it shows a sort of gathering against the busy star field.
