John Herschel discovered NGC 2123 = h2983 on 30 Nov 1834 and reported "pB; vS; R; vglbM; 12"." In 1926, Robert Innes described it visually as a "small globular cluster. = 9mag, with outliers; very condensed." (26-inch refractor, Union Observatory).

300/350mm - 13.1" (2/18/04 - Costa Rica): very faint, small, round, 30" diameter. This LMC cluster is located 50' NE of mag 4.3 Delta Doradus. In the 105x field it is 8' SE of mag 8.0 SAO 249373 and is collinear with two mag 10.5-11.5 stars 5' and 10' NE, respectively. DSFG notes this is a "relatively bright and compact group".
