This is main telescope at OPD/LNA. It was commissioned in 1981. Its focal ratio at the Cassegrain focus is f/10 and the optical design is Ritchey-Chrétien. At the Coudé focus the focal ratio is f/31.2 after some conversions from a secondary that delivers a f/150 beam. The telescope points under control of a program developed by LNA and UFMG. The absolute precision of the pointing is about 15 arcsec. This telescope is used in photometric and spectroscopic projects.
0.6m Boller & Chivens (IAGUSP)This telescope was installed at the OPD in 1992 through an agreement between the University of São Paulo and LNA. The focal ratio at the Cassegrain focus is f/13.5. The optics is of Ritchey-Chrétien type. The pointing system for this telescope is very similar to the one developed for the 1.6-m telescope. The telescope is used exclusively for photometry.

This telescope is the result of a coffee trade with the late East Germany in the sixties. For many years it was stored near Brazópolis and finally installed at OPD in the beginning of 1983. It is a classical Cassegrain with parabolic/hyperbolic primary/secondary. The equivalent f-ratio is f/12.5. The instrument has manual pointing. It is used exclusively for photometry.
