William Lassell

Lassell discovered 4 NGC objects. The first was NGC 3121, a galaxy in Leo, found on March 31, 1848 with his 24" reflector at Starfield Observatory near Liverpool (see AN #635). The object is contained as #26 in Arthur Auwers' list of new nebulae; see: William Herschel's Verzeichnisse von Nebelflecken und Sternhaufen, Königsberg 1862. NGC 3121 is identical with NGC 3119, found by his assistant Albert Marth with the 48" at Malta in 1863 (#194 in the reference below). NGC 7285 is a galaxy in Aquarius, discovered in 1863 with the 48" at Malta. The 3rd object is the galaxy NGC 7489 in Pegasus. It was found on September 14, 1863 and is included as #523 in A Catalogue of new Nebulae discovered at Malta with the Four-foot Equatoreal in 1863 to 1865, Mem. R.A.S. 36, 53 (1867). The last object is the galaxy NGC 2620 in Cancer, found at Malta on March 5, 1863 (#125). It is unknown, why NGC 7285 is not in the Malta catalogue.
