 20" f/4- D20

 

The completely redesigned D20 features a 20" primary mirror by legendary optician Carl Zambuto.  At f/4 this is the fastest mirror Carl has ever offered commercially, and of course, Webster Telescopes brought it to you first.

Leave your ladder at home.  With only a 76" maximum eyepiece height, you are going to be observing with your feet on the ground most of the night.  A single step up on a stepstool is all most observers will need at zenith. 

Easily moved around and assembled by a single person.  Leave it assembled in the garage and roll it out for instant use.  Disassembled, it fits under the cap of any standard pickup truck or SUV. 

The D20 was designed from day one to utilize the Argonavis and ServoCAT.  No bulky controller boxes or tangles of wires hanging outside of the scope waiting to become damaged. Even the wires for the Argonavis run inside the trusses.   Here at Webster, we believe out of sight is out of harm's way (and of course, it doesn't hurt that it looks great too). 

Because the D20 is a Webster, we include all these "options" the other guys charge you extra for:

Feathertouch 2 speed focuser with deluxe adjustable base

Spherical Bearing Mirror Cell

3.5" 1/10th wave Secondary Mirror

Telrad Finder
