― NGC Notes by Harold Corwin

Courtney Seligman

Albert Marth observed eight nebulae, subsequently listed as NGC 1109, NGC 1111, NGC 1112, NGC 1113, NGC 1115, NGC 1116, NGC 1117 and NGC 1127, on a single night in 1863. Of those, only three have positions that seem to more or less reliably correspond to actual objects -- NGC 1115, NGC 1116 and NGC 1127. NGC 1117 can be fit to a nearby galaxy, but its identification is far less certain, and NGC 1113 cannot be convincingly connected to any object. Still, that is not as complicated as the situation for NGC 1109, NGC 1111 and NGC 1112, each of which has two or more candidates for what Marth might have observed, and for several of those candidates, more than one suggestion as to which of Marth's objects a given candidate might correspond to; so for those NGC entries there is little if any hope that there will ever be a convincing argument for which objects correspond to which entries.
