We describe the optical design of a sky survey system comprised of small aperture telescope tube assemblies mounted
on a common semi-equatorial frame with a single polar axis. It is the first ground-based instrument to create a map of
transients down to optical m=17 by imaging a fixed-declination strip of the sky on a nightly basis. The system is fully
remotely automated and physically robust. The mount tracks the sky using a motion controller, drive motor, and a laser
rotary encoder. The prototype configuration is suited to house up to 6 telescopes on the current mount and is easily
expandable to accommodate up to 30 telescopes which would enable full sky coverage if one system each were placed in
the Northern and Southern Hemispheres1.© (2008) COPYRIGHT SPIE--The International Society for Optical Engineering. Downloading of the abstract is permitted for personal use only.
