As part of a collaboration between the University of New Mexico and the University of Texas at Austin, design of the second iteration of the CCD/Transit Instrument (CTI-II) is underway. With a one degree square scientific focal plane mosaic of CCDs operated in the time-delay and integrate (TDI) readout mode, the stationary, 1.8-m telescope will accomplish a multi-bandpass photometric and astrometric imaging survey of more than 300 square degrees of the sky. The science drivers for the design (described at this meeting) dictate that CTI-II:
• sample the time-domain with a cadence of one sidereal day for a span of years,
• provide accurate (millimagnitude) photometry in multiple bandpasses to faint limiting magnitudes, and
• achieve milliarcsecond precision astrometry.
We describe the goals of the survey, the telescope, and the ancillary instrumentation designed to accomplish these goals.
