John Herschel discovered NGC 2307 = h3068 (along with NGC 2305 = h3067) on 30 Nov 1834 and noted "vF; pL; lE; in the parallel." His position is accurate.

400/500mm - 18" (4/5/16 - Coonabarabran, 236x): slightly larger and fainter of a pair with NGC 2305 4' NNW. Appeared moderately bright and large, roundish, contains a bright elongated core or "bar" oriented NW-SE [~40" in length] with a diffuse halo ~1.3' diameter.
