The Questar Standard 3.5 (3.5" aperture, 1300mm focal length, f/14.4, Maksutov Cassegrain) has long been regarded as the finest personal telescope in the world. In addition to the telescope's legendary resolution, flatness of field and contrast, the Standard has integrated features that are unavailable with other telescopes.

The control box has two (2) viewing ports with flick knob selection. It provides three power changes per eyepiece, an internal finder and two telescopic powers. Included also are a star-diagonal prism, solar filter for finder lens, off-axis glass solar filter, and focusable eyepiece diopter. The barrel rotates for viewing height adjustment and is silk-screened with a functional Moon Map. The removable dewcap is a Star Chart.

The equatorial fork mount is brushed cast aluminum, aircraft polyurethane painted, with friction drive alt-azimuth controls. It includes an AC powered synchronous clock drive motor and declination clamp. The setting circle for Right Ascension and Declination is fully functional. The RA circle is universal for northern and southern hemispheres.

The Standard stores in a carrying case that has pockets for the included tabletop legs, extra eyepiece, solar filter and AC adapter cord, as well as a pocket for the optional Powerguide Controller.
