Albert Marth discovered NGC 7532 = m 541, along with NGC 7530 and 7534, on 1 Oct 1864 and noted "vF, vS, lE." His position is accurate.
300/350mm - 13.1" (9/29/84): brightest and largest of trio, fairly faint, small bright core, slightly elongated.
13.1" (11/5/83): very faint, small, round. Second of three with NGC 7530 3' SW and NGC 7534 2' NNE. Located SE of a mag 7 star in the NGC 7532/7556 group.
400/500mm - 17.5" (8/1/87): brightest and largest of three on a line with NGC 7530 4.1' SW and NGC 7534 2.1' NE. Fairly faint, fairly small, elongated NW-SE, small bright core, stellar nucleus. Located 6.8' SE of mag 7.5 SAO 146580.
600/800mm - 24" (8/7/13): brightest and largest in a trio of NGC galaxies (KTS 71) in a 6' string oriented SW to NE. At 375x appeared moderately bright and large, elongated 5:2 NNW-SSE, well concentrated with a small bright round nucleus. A mag 10.7 star lies 2.3' S. NGC 7534 is 2' NE and NGC 7530 is 4' SW. Situated 6.8' SE of mag 7.1 HD 219200.
