Corwin's Notes
=====
NGC 7502 is a triple star (at first glance a double) 32 seconds of time west,
and 1 arcmin north of the nominal position from a single observation by Frank
Muller with the 26-inch refractor at Leander McCormick. The combined
magnitude of the stars, their separation, and their position angle all agree
with Muller's estimates (15.8, 0.3 arcmin, and 290 degrees). In addition, he
notes the possibility that the object is only a double star. The southeastern
"star" is itself double which undoubtedly added to the impression of
nebulosity.
-----
Looking at the DSS2R and IR images, I no think believe that the southeastern
star is double. I've changed the type and notation in the position table to
reflect this.
