William Herschel discovered NGC 4460 = H I-212 = H II-750 = h1289 on 10 Apr 1788 (sweep 830) and noted for I-212 "cB, pL, E." His position is poor -- CH's reduction places it 8.6' too far northwest (all the preceding objects in the sweep are too far north). He found it again 17 days later (sweep 833) and logged II-750 as "pF, pL, E sp nf." His position was just 2' northeast of center. JH realized the equivalence and combined the two H-designations in the GC.
300/350mm - 13.1" (4/12/86): moderately bright, pretty edge-on 4:1 SW-NE, moderately large, brighter core. A pretty double star ∑1645 = 7.5/8.1 at 10" is in the field 8.5' SW. Member of the CVn II Group (brightest member M106).
