Corwin's Notes
=====
NGC 6815. On POSS1, this appears to be a cluster about 20' by 10', elongated
roughly in position angle 135 deg, centered about 4 arcmin southwest of JH's
position. It's not too obvious on the photographs, but could well stand out
while sweeping with a large telescope.
In the DSS2R image, I make the cluster a couple of arcminutes broader, and put
the center about an arcminutes to the northwest, but it still appears
elongated in about the same position angle.
JH marked the position "+-" in his 1833 list, and the cluster is indeed
scattered enough that its position could be moved around inside a five-
arcminute area without anyone noticing ...
Steve's Notes
=====
NGC 6815
17.5" (6/15/91): at 100x, ~100 stars mag 10-14 in a large 30' field elongated ~E-W. Includes six brighter mag 10-11 stars although most members are mag 12-13. Scattered appearance with no rich sections although over unresolved background haze. A mag 8 star is off the NW edge. Difficult to define borders as basically appears as a Milky Way field enhancement.
