Corwin's Notes
=====
NGC 7522. There is no trace of a nebula matching Muller's description
(magnitude = 16.0, diameter = 0.3 arcmin, irregularly round, suddenly brighter
in the middle? [the query is Muller's], star 10 in position angle 75 deg,
distance 3.2 arcmin) in his published position. Unfortunately, no sketch of
the field survives among the unpublished Leander McCormick papers.
ESO has suggested that the number might apply to an extremely faint galaxy
near the NGC position, but it is almost certainly too faint to have been seen
even in the Leander McCormick 26-inch refractor -- it is barely visible on the
blue POSS1 print.
Another possibility for Muller's object is the faint star about 2 minutes of
time following the published position. It has the correct distance and
position angle from a brighter star to the east-northeast, is about of the
right magnitude, and is offset from the published position by about the same
amount and in the same direction as many other of the nebulae in the Leander
McCormick lists. I stress, however, that this is just another possibility for
the identity of N7522. It could well be wrong, and Muller's nebula truly
lost.
