NGC 3848
NGC 3848, III 35, GC 2531
History and Accurate Positions for the NGC/IC Objects (Corwin 2004)
NGC 3848 is probably NGC 3822, and NGC 3852 is probably NGC 3825. The two questionable identifications are a pair found by William Herschel on 15 March 1784, III 35 and III 36. He describes them as "Two on parallel, 3 or 4 arcmin distant. Both eF, vS," and assigns a single position to the pair.
Dreyer, in the Notes to his 1912 edition of WH's papers, claims for N3848, "Observed by Bigourdan, place correct." For N3852, he says, "RA possibly 1 minute too great (see II 64 [NGC 4352]). Not found by Bigourdan."
This is curious, as Bigourdan clearly states "Not seen, at least in a sure way" for N3848, and "Not seen" for N3852. Perhaps there is a note in one of Bigourdan's Comptes Rendus papers. In any case, Bigourdan has precise measurements for NGC 3822 and NGC 3825, and identifies them correctly. They are 2 minutes west (not 1 minute) of WH's positions for N3848 and N3852, and they match WH's description well.
Other fainter galaxies in the area include NGC 3817, 3819, 3820, 3833, and several CGCG/MCG objects. Since N3822 and N3825 are the brightest of the lot, they are most probably the ones that WH picked up.
Historical observations
William Herschel (c.1784)
Synonyms: H III-035
Discovered in 1784 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "Two on parallel, 3 or 4' distant, both eF, vS." The second object is NGC 3852.
Published comments
Sulentic & Tifft (1973)
The RNGC (Sulentic and Tifft 1973) notes that this is a 15.0 mag galaxy. Their coded description reads R,BM,DIFHALO.
