John Herschel discovered NGC 1783 = h2726 on 13 Dec 1835 and recorded "pB, L, R, gbM, 2'." On a second sweep he called it "B, L, R, vgpmbM, resolvable 3'."
300/350mm - 13.1" (2/17/04 - Costa Rica): moderately bright, fairly large, round, 2.0' diameter, fairly smooth surface brightness. Appears to be a globular cluster as it is well-detached in the field with a fairly crisply defined edge, increasing to a brighter 1' core. NGC 1805 lies 20' ESE.
600/800mm - 30" (10/18/17 - OzSky): at 202x and 264x; Intensely bright LMC cluster! Very large, roundish, 2.5'-3' diameter, highly concentrationed with a large, brilliant core that gradually increases towards the center. At 429x; very granular or mottled appearance. A number of extremely faint stars and/or clumps of stars (too many to count) popped in and out of visibility.
