The Small and Moderate Aperture Research Telescope System (SMARTS) Consortium operates four small telescopes on Cerro Tololo in Chile. Membership in SMARTS is open to individuals or institutions, including international partners.

The SMARTS 0.9-meter Telescope was constructed in 1965 by Boller & Chivens and is a closed-tube design telescope, with instruments attached at the bottom at the Cassegrain focus. The telescope has been operated by the SMARTS Consortium since February 2003. As of August 2020 the 0.9-meter is used for direct imaging with a dedicated 2048x2046 CCD detector. A CCD-based autoguider, which looks at a small off-axis field, is permanently installed.
