NGC/IC Project Restoration Effort

===== NGC 1845 is a large, scattered cloud of stars in (or superposed on) the LMC. Its center is northwest of JH's 9th magnitude star by 2-3 arcmin, and I make the approximate size on DSS1 15 x 10 arcmin. On the DSS2R (which I examined in November 2013), it appears to be somewhat larger (22 x 12 arcmin), and centered further west than I'd placed it before. It seems to be composed not only of an SMC star cloud (including a couple of small clusters and a nebula), but of a few brighter, superposed Galactic stars as well. JH gives us two positions for it, one from Sweep 513 for "The general middle of the same cluster" (05 07 47.5, 160 45 01 for 1830.0); the second from Sweep 751 for "A star 9m the second in magnitude and near the centre of clustering groups which run together and form a cluster which fills the whold field. v l comp M; [sts] 11 ..... 16 m" (05 08 08.1, 160 48 55, again for 1830.0). The position in the NGC is a mean value of JH's two estimates.

===== NGC 1845 25" (10/10/15 - OzSky): at 318x; very large star cloud/association (LH 26) completely filling the 19' field. At the northeast end is the small open cluster S-L 232, which is often taken as NGC 1845. It appeared as a moderately bright, nebulous patch, roundish, 30" diameter, unresolved. A mag 11.2 star is 0.9' SW. The star cloud generally trends northeast to southwest (from S-L 232), stretching ~20'x10', and includes the open cluster NGC 1833 and 1837 at the southwest end. The cloud includes a stunning mix of bright (a few mag 9.5 stars are Milky Way stars), numerous mag 12-13 stars and faint stars over the glowing LMC background haze of myriad unresolved stars.
