We present a 1.4 square degree survey of the Praesepe open cluster complete to I = 21.3 and Z = 20.2. This corresponds to masses down to 0.06M&sun; and 0.075M&sun; for an assumed cluster age of 1.0 or 0.5 Gyrs respectively. Over fifty new Praesepe candidate members have been discovered with masses less than 0.25M&sun; . We discuss plans to establish proper motions of identified Praesepe candidates, and to measure NIR photometry of our candidates.
