Hard-X-ray observations are an efficient way to discover accreting sources at high redshift. A preliminary status report is given of near-IR observations of three, ˜100-square-arcminute fields centered on ChaMP fields MS2053.7-0449, CLJ0152.7-1357 and LP944-20. The deepest observations, centered on MS2053.7-0449, reached J=22.5mag, Ks=20.3mag, using a 1.5σ detection threshold. A catalog of the infrared sources detected in both filters in each field has been prepared and is being combined with CHANDRA/ChaMP observations to produce an initial matched catalog of IR and X-ray sources. The near-IR data were taken with the ISPI near-IR imager on the Blanco 4-m telescope on Cerro Tololo.
