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.
