William Herschel discovered NGC 2775 = H I-2 = h564 on 19 Dec 1783 (internal discovery #16 in sweep 57). His summary description from 5 sweeps reads "cB, cL, R, vgbM, with nucleus." On 23 Dec 1827 (sweep 116), John Herschel wrote, "vB; R; psbM; 2' diam; the hazy border perhaps extends further; resolvable??" Samuel Hunter, the 72" observer on 28 Mar 1861, also thought he could resolve this galaxy, reporting "R, vgbM like a glob. Cl, I see stars plainly at times."

200/250mm - 8" fairly bright, bright core, elongated.

300/350mm - 13" (2/23/85): bright, fairly large, elongated NNW-SSE, bright core, stellar nucleus.

400/500mm - 17.5" (3/29/89): bright, very large, elongated 4:3 NNW-SSE, small very bright core, stellar nucleus, large faint halo. Near the edge of the field is NGC 2777 11' NNE (physical companion) and NGC 2773 13' NW (background galaxy).
