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)
