NGC 4752 is a 14.5 mag bright spiral galaxy of the Hubble type Sbc in the constellation Haar der Berenike in the northern sky . It is estimated to be 502 million light years from the Milky Way and about 105,000 light years across.
In the same area of the sky is u. a. the galaxy NGC 4689 .
The object was discovered on April 12, 1784 by Wilhelm Herschel with an 18.7-inch reflector telescope, who described it as “vF, S, E, r”.
Perhaps NGC 4752 with CGCG 071-058 equate, because Herschel's description fits exactly, but its location was wrong. Subsequent astronomers , u. a. Bigourdan too , could not repeat his observation.
