History

This galaxy NGC 7741 was discovered by William Herschel on 10 September 1784 and is listed as II 208. He noted: «Faint, considerably large, round, very gradually brighter in the middle, south following a star.» [463]

The faint galaxy NGC 7735 was discovered by John Herschel on 5 September 1828. He listed it as h 2263 in his «Slough Catalogue» and noted: «Very faint; a star 14 mag with a nebulous brush extended towards the star, and on its south preceding side; position from the star by diagram = 250° or 260°. This disagrees with my Father's description of II. 208, which is said to be south following a star, but this may be a mistake for south preceding; but then lso the R A disagrees 2m and the P D 6'. It can hardly, therefore be the same object.» [466] The position he gave matches the small elliptical galaxy UGC 12744.
