Questar 7 Light Weight


Questar¡¯s commitment to quality, on which it has built its worldwide reputation, is immediately apparent in the superb resolution and mechanical precision of the Questar Titanium Light Weight Classic Seven. Those who want more aperture than the Questar 3.5 provides will marvel at the lighter packaging, increased power and
quadrupled light grasp available with its larger offspring. The Light Weight Titanium Classic 7¡± is an astronomical telescope that is completely portable. You can use it on a tripod, table with its optional equatorial mount and legs, or with Questar¡¯s Large Astro Pier.

Our Classic 7¡± has been redesigned with changes to all internals to incorporate many new technologies that we¡¯ve borrowed from our exiting aerospace and surveillance satellite experience. All of our internal stainless components are now titanium. To refine internal components to rapidly chill our optics and dissipate heat, we have done extensive heat transfer analysis. ( Fourier analysis for isotropic material analyzing conduction, convection and radiation heat transfer, optimizing Emissivity, Prandtl number and Nusselt number)
