History and Accurate Positions for the NGC/IC Objects (Corwin 2004)

NGC 7045 is a double star. JH says of it "eF; field feebly illuminated by moon, but I remained satisfied of its reality." He has only this single observation of it in Sweep 79. His position is only 30 arcsec north of the pair of stars, so the identification is pretty certain.

Spitaler first identified the object as the double. Dreyer noted in the NGC that d'A failed to find the object on two nights. The pair was either too faint for his telescope, or he dismissed them as being obviously stellar.

A curiosity: Bigourdan has six observations of the double on two different nights, and apparently thought it nebulous on both nights. He used it as the comparison object for his estimated positions for IC 5097 and IC 5098 (both of which see).

Historical observations

John Herschel

This object was recorded only once by Sir John Herschel, observing in faint moonlight. He described it only as "extremely faint."

d'Arrest

d'Arrest looked for it twice, and although the nearby galaxy NGC 7046 was seen, he could not find it.

Spitaler

Spitaler's observation showed it was not a nebular object, but a couple of very faint stars close together.

Published comments

Sulentic & Tifft (1973)

The RNGC (Sulentic and Tifft 1973) notes that this is a nonexistent object. Their coded description reads EL,BM.
