John Herschel discovered NGC 1816 = h2748 on 2 Jan 1837 and recorded "vF, R, another nebulous knot [along with NGC 1814] in the cluster [NGC 1820]". Shapley and Lindsay (1963) group NGC 1814, 1816 and[NGC 1820 together and note "bright scattered stars in nebulosity", with a size of 6.8' x 4.5'.

600/800mm - 24" (11/18/12 - Magellan Observatory, Australia): small, brighter "knot" on the west side of the LMC association NGC 1820 = LH 19. At 200x, a couple of stars are resolved within the 18" glow. Forms a pair with slightly brighter NGC 1814 2.5' SSW.
