Corwin's Notes

===== NGC 6659 appears to be a clump of about 20 stars between 10 and 15 mag covering an area about 9 x 5 arcmin. JH describes it tersely, "A v poor cluster 8th class." His position is about 2 arcmin southwest of the center of the clump of stars. Archinal adopts the position of HD 342450, near JH's position, as that for the object, yet has its type listed as "nf?" -- "not found?" Perhaps; but I have nevertheless adopted my position from the DSS2R.

Steve's Notes

===== NGC 6659 17.5" (8/3/97): at 100x a very unimpressive scattered group of ~15 stars elongated SW-NE is visible just south of a mag 9 star. This weak collection includes 5 brighter mag 10-11 stars and a mag 9.5 star on the south end. I would have passed over this grouping without using a GSC plot centered on the mag 9.5 star at JH's position. At 220x, ~20 stars were counted in a 7'x3' region over some background Milky Way haze. A small extension of this faint glow was seen to the south of the group with a few mag 15 stars resolved. Looks entirely like a weak asterism and it is very surprising that it was logged as a cluster. Listed as nonexistent in RNGC.
