Discovered in 1784 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "F, pS, E, following a pretty bright star."
The RNGC (Sulentic and Tifft 1973) notes that this is a 13.5 mag galaxy. Their coded description reads E,R,BM.
Steve Coe, using a 13.1" f/5.6, notes: "NGC 7454 Pretty faint, pretty small, round and somewhat brighter in the middle at 100X. There is a pretty bright star at one edge of the galaxy."
POSS: m12 * 54" NW, m13.5 * 1'.05 NNW: implies 15cm size 1'.0x0'.7.
15cm - mod f @ 80x, making sm triangle w/m11.5 * NW and m13.5-14 * NNW. elong
pa135, 1'.2x0'.8. seems about as long as distance to m13.5-14 *, but
maybe only as long as sep to mm11.5 *. mod even concen to f *ar nuc. BS,
