| The
Questar Seven (7" Maksutov Cassegrain, 2400mm Focal Length,
f/13.4) has
the same optical perfection and Maksutov design as its little
companion the Questar 3.5 telescope. Both are of the same superb
quality, but the Questar Seven has twice the resolving power,
four times the light grasp and two times the effective focal length
of the Questar 3.5.
The
Seven is a powerful instrument for both astronomical and terrestrial
observing and photography, and in modified form is used extensively
in many special and industrial applications. Like its famous companion
it delivers resolution of planetary and lunar details to its theoretical
limit, and photographs lunar, planetary and deep sky objects normally
beyond the capability of a telescope of its size.
Like
the Questar 3.5, the Seven is photo visual, with the same built
- in controls, such as finder system, axial photographic port
and power changes by just flipping a lever. It has a centrally
supported mirror with linear precision bearings and internal focusing
which permits the freedom of a movable focal plane for the best
use of visual and photographic accessories with virtually no image
shifting typical of other telescopes on the market. The Questar
Seven will bring observatory level performance to you in a portable
package that can be set up in just a few minutes.
