Corwin's Notes
=====
NGC 6669 is most likely the asterism of five faint stars just north of Marth's
position. There are fainter stars involved that may have added to the
nebulous appearance of the object. This is of an appropriate size and
combined magnitude that he would probably describe it as he did, "eF, pL."
Wolfgang followed the LEDA group's lead in assigning this number to a 16th
magnitude galaxy with a 12th magnitude star superposed well off Marth's place.
Had Marth seen this object, he would certainly have mentioned the star. I
think that the galaxy is faint enough, however, that the star would mask it,
even at the eyepiece of Lassell's 48-inch reflector.

NGC 6669
18" (7/21/04): at 225x, this is just an inconspicuous, 20" hazy patch that is lively. A couple of extremely faint stars are on the verge of visibility. Several bright and faint pairs are in the field including a faint, close pair 2.4' NW.
17.5" (8/7/02): at 100x, I noticed a very faint, small hazy patch at the plotted position. At 263x, the glow was still faint, ~1' diameter, with an irregular surface brightness with three very faint stars resolved (two of these are on opposite sides of the glow). Located 10' NE of a mag 6.8 star.
