Corwin's Notes
=====
NGC 1117 may also be IC 1855 (which see; also see NGC 1109).
There is a double galaxy just 30 seconds of time east of Marth's position;
this is probably his object. However, his only description is "close to a
small *". Unfortunately, he does not tell us the direction of the "small *",
so we do not know which of the galaxies is the one that he saw. Neither is
obviously stellar on the sky survey plates/images, and the faint star near the
southern galaxy is probably beyond his limit, even with a 48-inch telescope.
So, I've listed both objects with colons. This is a candidate for visual
inspection: Does one galaxy appear more obviously stellar than the other?
Steve's Notes
=====
NGC 1117
17.5" (11/28/97): very faint, very small, slightly elongated N-S. Appears as a barely resolved double system oriented N-S, ~30"x20" total size. The object at the south side appears to have a stellar nucleus. The northern object has a 20" halo and appears larger. The centers of this pair are only 24" apart.
