NGC 5653 = IC 1026, which see.
Discovered in 1785 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "pB, pL, R, bM."
Burnham calls it a 12.9 mag spiral galaxy in Bootes, measuring 0.5' x 0.4', which is pretty faint, pretty small, round and brighter in the middle.
The RNGC (Sulentic and Tifft 1973) notes that this is a 13.5 mag galaxy. Their coded description reads R,BM,IRRDIFHALO DKPCHS NP END.
Steve Coe, using a 13" f/5.6, notes: "Pretty faint, pretty small, round, bright middle at 100X."
