R.J. Mitchell discovered NGC 7752 on 22 Nov 1854 while observing NGC 7753 at Birr Castle He noted "south preceding NGC 7753] is a vS oblong nebula, resolvable?" It was observed again in 1857, but no offset or sketch was made. Heinrich d'Arrest independently found this galaxy on 24 Sep 1865, though confused the orientation and placed NGC 7752 1.5' north of NGC 7752, instead of 1.6' south. As a result the relative positions in the NGC are incorrect.

300/350mm - 13.1" (9/22/84): faint, very small, elongated ~E-W. Forms a close pair with brighter NGC 7753 2' NE. A mag 14 star is 1.2' NE of center and situated between the galaxies.

400/500mm - 18" (7/14/07): fairly faint, fairly small, elongated 3:2 WNW-ENE, 0.5'x0.3', even surface brightness. Fainter of a double system (attached at end of spiral arm) with NGC 7753 just 2' NE. A mag 14 star lies between the two galaxies

900/1200mm - 48" (10/28/19): at 375x and 542x; bright, elongated 2:1 WNW-ESE, 0.6'x0.35', irregular shape, large bright core that bulges at the center. Situated at the end of the western spiral arm of NGC 7753 [2.0' SW of center].
