We present results regarding the optical counterparts of the 5-ks Chandra observations of the Boötes region of the NOAO Deep Wide-Field Survey (NDWFS). This survey is unique in the unprecedented large ( ˜9 deg2), contiguous region imaged in X-ray and in the complementary deep optical and near-IR observations provided by the NDWFS. We detect optical counterparts for 98% of the 3,213 X-ray detected sources within the NDWFS area. The optical colors suggest that the bright galaxies are a combination of z<1 massive early-type galaxies and bluer star forming galaxies whereas the majority of the bright stellar sources are quasars at redshifts z ˜1-3. We select a large sub-sample of objects with large X-ray to optical flux ratios which are likely high redshift and/or obscured AGN. The 75 X-ray sources with no optical counterparts to R ˜26 have hard X-ray spectra and are also likely to be high redshift obscured AGN.
