WASP0 is a prototype for what is intended to become a collection of wide-angle survey instruments whose primary aim is to detect extra-solar planets transiting across the face of their parent star. The WASP0 instrument is a wide-field (9-degree) 6.3cm aperture F/2.8 Apogee 10 CCD camera (2Kx2K chip, 16-arcsec pixels) mounted piggy-back on a commercial telescope. We present results from analysis of a field in Pegasus using the WASP0 camera, including observations of the known transiting planet around HD 209458. We also present details on solving problems which restrict the ability to achieve photon limited precision with a wide-field commercial CCD. The results presented herein demonstrate that millimag photometry can be obtained with this instrument and that it is sensitive enough to detect transit due to extra-solar planets.
