I didn't make a careful survey of possible cluster members but picked up the following two galaxies: PGC 127867, situated 9.5' WSW, appeared faint, very small, round, 12" diameter. A mag 11.0 star is 2.4' ENE. ESO 113-019, located 10.2' WNW, appeared extremely faint, very small, round, 12" diameter, low surface brightness.

John Herschel discovered NGC 432 = h2391 on 6 Oct 1834 and logged "F, S, R." No position was determined on that sweep. On a later sweep he noted "pF, S, R, gbM, 15 arcseconds, has a star 12th mag following" and commented the "place is liable to some error".

600/800mm - 25" (10/15/17 - OzSky): at 397x; fairly faint, small, round, 25". Contains a small bright nucleus that gradually increases to a faint stellar peak. Located 35' NE of mag 5.35 Iota Tucanae. NGC 432 is the brightest member of the unstudied cluster ACO S137 (distance ~365 million l.y., richness class 0).
