Otto Struve discovered NGC 7451 on 7 Dec 1865 with the 15-inch refractor at Pulkovo Observatory at St. Petersburg while unsuccessfully searching for Comet Biela. His position is 3' south of UGC 12299 (common offset with his other objects). Bigourdan's "corrected" position from 7 Nov 1885 (repeated in the IC 2 notes) is 5.8' too far southwest, perhaps an error with the offset star.

400/500mm - 17.5" (8/27/87): fairly faint, fairly small, elongated WSW-ENE, weak concentration.
