Corwin's Notes

===== NGC 1838 is a scattered and pretty poor association in the LMC, perhaps including several superposed Galactic stars. JH's 7th magnitude star is on the western edge, so his position is off of the more modern ones that point to the center. I make the size 7.5 x 7.0 on DSS1. The much smaller and fainter LMC cluster SL 225 is on the southwestern edge of NGC 1838; it is probably not associated with the NGC object.

Steve's Notes

===== NGC 1838 30" (10/14/15 - OzSky): excellent scattered cluster/association in the LMC. Includes many brighter mag 11.5-13 stars along with dozens of fainter stars. Perhaps 75 stars down to mag 15 are resolved in a 7' region. Located just east of mag 8.2 HD 33617 with mag 10.2 HD 269035 at the southeast edge. There are three Shapley-Lindsay clusters (not specifically mentioned by Herschel) at the edges. S-L 225, at the southwest edge, appeared fairly bright, round, 50" diameter. Several mag 14-16 stars are resolved, particularly along the north side. Located 2' SSE of mag 8.2 HD 33617. A mag 11.7 star is 1.3' WSW. S-L 230, at the northern edge, appeared very bright, fairly small LMC cluster, 30"x20" ~N-S, clumpy. At 394x, a brighter star is resolved along with a few very faint stars and a quasi-stellar knot. It was too densely packed for additional resolution. Just 1' SW of S-L 230 is S-L 229, a pretty faint small glow, ~20" diameter, with no resolution.
