NGC 5004 is a lenticular galaxy in the constellation Coma Berenices.[1][2] The object was discovered by astronomer William Herschel in 1785, using an 18.7-inch aperture reflector telescope. Due to its moderate apparent magnitude (+13), it is visible only with amateur telescopes or with superior equipment.
