Discovered (May 1, 1785) by William Herschel (and later listed as NGC 4711)
Discovered (Mar 21, 1903) by Max Wolf (5-37) (and later listed as IC 3804)
A magnitude 13.4 spiral galaxy (type SBb??) in Canes Venatici (RA 12 48 45.7, Dec +35 19 58)

IC 3805
Recorded (Mar 21, 1903) by
Max Wolf (5-38)
A pair of stars in Canes Venatici (RA 12 48 42.4, Dec +38 15 15)

IC 3806 (= PGC 43303)
Discovered (May 5, 1904) by
Royal Frost (1039)
A magnitude 13.6 spiral galaxy (type Sa?) in Coma Berenices (RA 12 48 55.4, Dec +14 54 26)
Based on a recessional velocity of 1410 km/sec, IC 3806 is about 65 million light years away (although another measurement yields a recessional velocity of 3175 km/sec, which would correspond to a distance of 150 million light years). Using the 65 million light year distance, its apparent size of 1.9 by 0.65 arcmin corresponds to about 35 thousand light years (or more than twice that size if the larger distance is correct).
