SMARTS Telescopes' Histories


The 0.9-m telescope (also called the 36" telescope) was constructed in 1965 by Boller and Chivens. It is a closed-tube Cassegrain design which has a visible-light imaging capability (with a 2K CCD). It has found a great deal of use as a stable photometric and astrometric instrument. The mounting is a single-arm equatorial.  Click here for more details of the history of the 0.9m...

The Yale 1.0-m telescope, originally sited in Bethany, CT, was moved to CTIO in 1972. Between 1998 and 2002 it was run by the YALO consortium. The 1.0m has a very similar design to the 0.9m in optics and mounting. As pictured, the 1.0m sports the ANDICAM, which takes pictures simultaneously in the optical and infrared, however ANDICAM has been moved to the 1.3-m. The 1.0-m currently uses a 4K optical imager called Y4KCam.

The 1.3-m telescope, formerly the southern-hemisphere 2MASS survey telescope, is a much more modern design than the other SMARTS telescopes, using a split-ring altitude-azimuth mount and an optical design optimized for work in the infrared. It fits very neatly into its dome. Here it is shown without the ANDICAM.

The 1.5-m telescope is an open-tube Cassegrain, again on a single-arm equatorial mount. It has been operated with both an imaging and a spectroscopic detector, and the option of two secondaries giving f/13.5 and f/8.  Currently, its instruments are the R-C Spec and CHIRON.
