Corwin's Notes
=====
NGC 6777 may be NGC 6752 (first suggested by Owen Gingerich in a Sky and
Telescope article which appeared in the February 1960 issue on page 207). If
so, there is a large error in La Caille's position.
Much closer to his position is a fairly close pair of 9th magnitude stars,
SAO 257685 and 257686. These were mentioned by Delisle Stewart in his Harvard
Annals 60 list, and were subsequently picked up by Andris Lauberts for ESO-B.
Would these two stars look like "the nucleus of a small comet" in the eyepiece
of La Caille's half-inch aperture quadrant? Probably (see the discussion of a
similar asterism, NGC 6634). But Gingerich's idea needs representation, too,
so both objects are listed, even if with colons and question marks.
