The Apache Point Observatory 3.5-m telescope, loated in the Sacramento Mountains of New Mexico at an elevation of 2.8 km, is awaiting the installation of the primary mirror. The design of this telescope includes a number of innovative features including a lightweight honeycomb borosilicate mirror, friction drives and encoding, and complete computer control to facilitate remote use. A 0.3-m telescope was attached to the telescope mount to monitor tracking and pointing performance. Currently, the telescope tracks open-loop to 0.3 arcsec rms over 10 min and points to 5 arcsec rms. Improvements to the servosystem and encoder mounting should make it possible to meet the goals of tracking to 0.2 arcsec rms and pointing to 1 arcsec rms.
