Questar Standard 3.5 Telescope

The Questar Standard 3.5 telescope allows you to observe through three magnifications, and toggle back and forth between them without you ever moving away from the eyepiece. This is achieved using the Questar Control Box which is designed to provide reliable convenience and safety.

The Questar Control Box for the Standard 3.5 telescope is located at the rear of the telescope and provides two imaging ports, with linkages and control levers which offer fast knob selection. This organization results in three magnification changes per eyepiece.

The three types of magnifications the Standard Questar 3.5 telescope provides is an Internal Finder of 100mm, magnification = 100 divided by focal length of eyepiece. Low magnification at prime focus, magnification = 1280 divided by focal length of eyepiece, and high magnification, which provides about 2x magnification when viewing through telescope.

For precise tracking of celestial objects the Questar Standard 3.5 telescope has an equatorial Fork Mount. Both of its axes has a manual friction drive control. The Right Ascension R.A. has a slip clutch which prevents a manual override of the tracking motor. There is a R.A. setting circle and a DEC circle with declination motion variable clutch lock. The drive provides very smooth tracking.

Described as the finest compact personal telescope in the world the Questar Standard 3.5 telescope is American made and offers convenience, designed at high industrial levels of durability and performance.
