Mag: B=15.1, V=?
NGC 7586. Marth's position, verified on at least a second night, and copied correctly into the NGC, falls near a galaxy meeting his description "eF, vS, alm stellar." For some reason, CGCG ignores this object and incorrectly puts the NGC number on a considerably fainter galaxy 17 seconds preceding and a full 20 arcmin to the south.
At least Hubble got the right object in his thesis.
Thomson, M.J. (1991) Three cases of identity errors of NGC galaxies as published in major astronomical catalogues. Q.J.R.A.S., 32, 17-24.
(Sulentic and Tifft 1973) notes that this is a 15.0 mag galaxy. Their coded description reads S,SM,LBM.
Notes: "17.5-inch: very faint, round, 20" diameter, slight central brightening. Located 3.8' NW of mag 9 SAO 128097 and collinear with a mag 12 star 1.3' SE of the mag 9 star. RNGC and CGCG incorrectly identify N7586 as CGCG 406-045 which is located 20' further S. N7586 is not listed in CGCG, MCG or RC3."
