The galaxy was discovered by William Herschel on 28 March 1786 using his 18.7 inch reflecting telescope and cataloged as III 542. He described it as «considerably faint, very large, of an irregular figure, 5' long 4' broad, south preceding a double star». [464] Dreyer included the galaxy as NGC 3074 in his «New General Catalog of Nebulae and Clusters of Stars» which was published in 1888. [313]
