William Herschel discovered NGC 3757 = H III-843 = h919 on 18 Mar 1790 (sweep 951) and noted "vF, stellar neb. North-preceding a small star." CH's reduced position is 1' northwest of UGC 6584 and the star is 1' east. JH reported "vF; R; 15". Has a vS star south-following rather more than a diameter from edge."

400/500mm - 17.5" (4/14/01): compact, high surface brightness glow, round, 25" diameter, very small bright core. A mag 13 star lies 1' E of center. Several galaxies are within 30' in a group (LGG 246).
