Observe through a Questar Seven Astro, and you'll see detail and clarity in the skies that you have never seen through a lesser scope, or even through many larger scopes. The larger the aperture of the scope, the greater the image-blurring effect of these microcells, as the larger scopes simply have to look through more of these turbulent cells than a smaller scope. This produces guaranteed total system performance at the Cassegrain focus of 1/8th wave or better. They all have larger light-scattering secondary or diagonal mirror obstructions than a 7" Questar Astro.

The first uses of telescopes in space were to look back at the earth for surveillance. Most commercial telescopes claim to be "diffraction-limited" (which is generally assumed to mean 1/4th wave accuracy). The knob focuses the scope by turning a spring-loaded 32-pitch stainless steel focus rod that acts directly on the mirror thimble to move the primary mirror within the optical tube. Simply this: a fanatical devotion to hand-crafted accuracy. I have compared my own Questar Seven to a 14" Schmidt-Cassegrain on deep space objects such as the Sombrero galaxy, the Saturn Nebula, and Omega Centauri. In essence, when observing, you are usually looking through bubbles of disturbed air - microcells typically 4" in diameter in the layer of the atmosphere nearest the surface of the Earth. A dust cap and thread-on lens shade are standard, as is a hard carrying case. 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. this was the last 12 produced and sold by the questar company and is in great condition with very little use.

Constant exposure to salt air can adversely affect the silver mirror coatings. Each optical element in a Questar typically tests out at a truly outstanding 1/50th wave accuracy (shaped to within four ten-millionths of an inch of perfection!) This scope is confirmed as being 1/8W by Questar, and quartz remains more stable during temperature changes. The Questar Seven has the same optical perfection and Maksutov design as its little companion the Questar 3.5 telescope. Click on a thumbnail to see full-sized image.
