John Herschel discovered NGC 2305 = h3067, along with NGC 2307 = h3068, on 30 Nov 1834 and recorded, "F; vS; R; makes a small triangle with 2 stars." His position is accurate.

400/500mm - 18" (4/5/16 - Coonabarabran, 236x): moderately to fairly bright, fairly small, slightly elongated NW-SE, 50"x40", sharply concentrated with a very bright small core. Bracketed by two close stars; a mag 12.5 star is 35" S of center and a mag 11.6 star is less than 30" E of center. Forms a pair with NGC 2307 4' SSE.
