In this magnification from an excellent amateur image of M81, faint companion Holmberg IX (UGC 5336) is visible.
This image was created by Martin Germano with his self-made 14.5" f/5 Newtonian.
This galaxy was first listed by Sidney van den Bergh and cataloged by him as
DDO 66 (Van den Bergh 1959).
Dwarf galaxy Holmberg IX was first so called in Eric Holmberg's study of groups
of galaxies (Holmberg 1969).
A formal description of this and another M81 group
dwarf was first provided by
Bertola and Maffei (1974).
It is an irregular galaxy of so-called Magellanic type (i.e., similar to the
Magellanic Clouds), closely resembling Local Group galaxy IC 1613.
