John Russell Hind discovered NGC 4125 = Au 28 on 5 Jan 1850 with a 7-inch Dolland refractor at George Bishop's private observatory in London. He noted "tolerably bright, but small." This was the second deep sky object he discovered after NGC 6760. In the next issue of Astronomische Nachrichten he added "of an elliptical form with a strong nuclear condensation." Hind's Crimson star is mentioned in the same note! Auwer listed this galaxy as #28 in his 1862 list of new nebulae.

400/500mm - 17.5" (3/20/93): bright, moderately large, very elongated almost 4:1 E-W, 2.5'x0.7'. A very bright elongated core and nearly stellar nucleus dominates the galaxy with much fainter extensions but overall the surface brightness is high. A mag 10 star is 2.4' ESE of center. Forms a pair with NGC 4121 3.6' SW.
