John Herschel discovered NGC 1800 = h2732 on 19 Nov 1835 and described it as "pB, pmE, gpmbM, has a star 13th mag following." His position and description is accurate.

Pietro Baracchi observed the galaxy on 2 Jan 1886 with the 48" Melbourne telescope. His sketch indicates a 13th magnitude "star" at the NW tip. At this position is a relatively large bright HII knot.

300/350mm - 13.1" (12/22/84): faint, small, elongated 3:2 WNW-ESE, even surface brightness. A mag 13 star is off the NE edge 1.3' from center. Brightest in a small group (LGG 108), along with UGCA 103 and UGC 106.
