NGC 5469 is a 14.1 mag bright lenticular galaxy of the Hubble-type S0 in the constellation Bear Keeper and 323 million light-years from the Milky Way.
It was discovered in 1883 by Wilhelm Tempel , who noted: “ III 59 [= NGC 5482] is 9s preceeding, 2 1/2 ′ south of a faint star 11m; the nebula is small and has in its center a faint star with very little nebular matter. Following the star 11m, there is at 15s, parallel to it [the star or N5482?] A nice round nebula, III, without a faint star [in the center]. This nebula is also new “The exact position of the observation is not certain according to Tempel's documents and is indicated as follows: either right ascension : 14/12 / 29.9; Declination : + / 08/38/52 or right ascension: 14/06 / 24.2; Declination + / 09/26/12.
