NGC 6925 may also be IC 5015, which see.
Discovered by Sir John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He recorded it as "B, mE, pslbM, 2.5' long, 40 arcseconds broad." On a second occassion he called it "pB, pmE, psbM, 80 arcseconds long, 20 arcseconds broad." His third observation was recorded as "B, L, mE in pos 6 degrees, psmbM, 3' long."
F, 3'x1', spiral.

Comments on papers by Harding (MNRAS, 74(8)), and Melotte (MemRAS 60(5)) describing objects foundon the Franklin-Adams plates; compares with plates taken with the Reynolds reflector (Helwan Obs Bull. 9-15):
NGC 6925 is an elongated spiral. [previously included in Class II-Spindle-shaped Nebulae]
(Sulentic and Tifft 1973) notes that this is a 12.0 mag galaxy. Their coded description reads S,EL,BM,TIWDIFARMS.
Coe, observing with a 13" f/5.6, notes: "Pretty faint, pretty large, much elongated 3 X 1 in PA 0, much brighter in the middle with an almost stellar nucleus at 135X."
