  We report our search for the cool white dwarfs belonging to the Galactic disk
by extending the NOAO Deep Wide-Field Survey. Narrow-band DDO51 photometry of
the Deep Wide-Field Survey's northern field was obtained using the 4m-Mayall
Telescope and the MOSAIC imager to separate cool white dwarfs from other
stellar types of similar T_eff. Follow-up spectroscopy of four white dwarf
candidates from our photometric search resulted in the discovery of two new
cool white dwarfs as companions to M dwarfs.
