John Herschel discovered NGC 1837 = h2769 on 3 Nov 1834. He observed this cluster on two sweeps and recorded it as "The last of three clustering groups (hazy)" and "the most condensed part of a large rich cluster of scattered stars which more than fills field." Archinal notes that brightest star is at 05 04 56.8 -70 42 57, close to Herschel's second position. It is not clear what other two objects he was referring to in the first sweep as only NGC 1833 is in the same field, though the star cloud (stellar association LH 24) containing these clusters extends to the northeast.

600/800mm - 25" (10/10/15 - OzSky): at 318x; this cluster is primarily a very elongated N-S string of stars with some unresolved haze. There was no filter response. A few brighter mag 12.5-13 stars are involved with a total of a dozen in the 1.2' string. NGC 1837 forms a 3' pair with NGC 1833 to the west-southwest. A star cloud extends to the north with several mag 12 stars, along with many faint stars in the wider field. This magnificent association (LH 26) is rich in bright and faint stars.
