Discovered in 1785 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "Two. The following [NGC 7541] pB. ,E in parallel, mbM, 4' long, 1' broad. The preceding [NGC 7537] vF, cS; 3 or 4' distant."
The RNGC (Sulentic and Tifft 1973) notes that this is a 12.5 mag galaxy. Their coded description reads EL,BM,HISB,INTDKPCH DIF PERIPH.
Houston notes that Admiral Smyth viewed this galaxy with his 6-inch refractor, noting that it appeared "so dim as to be only perceptible under settled gazing, and clock-work motion, when it faintly gleams among the telescopic stars in the field." Houston adds: "Yet my 5-inch moonwatch scope on a good night shows this 3' by 1' spindle, which I estimate as of visual mag 11.8."
Steve Coe, using a 13.1" f/5.6, notes: ""NGC 7541 Bright, large, elongated 4 X 1 in PA 90 and has a bright middle at 165X. Has NGC 7537 as a companion galaxy, and they are almost in the same PA of elongation."
