William Herschel discovered NGC 3414 = H II-362 = h773 on 11 Apr 1785 (sweep 396) and note "pB, pL." John Herschel made four observations (h773) while 8 observations were made at Birr Castle.

Bindon Stoney, using LdR's 72" on 6 Mar 1851, noted "Another neb eF, S. 2' np." Again on 23 Feb 1857 as well as 22 Mar 1857, R.J. Mitchell mentioned "about 1' np is vvF neb? lE." and "about 1.5' np [NGC 3414] there is a vvF patch of neby." These observations clearly refer to 2MASX J10511304+2800221 = PGC 93597, although it was not assigned a GC or NGC designation!

200/250mm - 8" (3/24/84): faint, slightly elongated.

300/350mm - 13.1" (3/24/84): bright, slightly elongated ~N-S, small bright nucleus, fairly small. Forms a pair with NGC 3418 8.5' NNE. Located 18' E of 44 Leonis (V = 5.6).
