Main Features

  • Lightweight and strong structure

  • Rapid thermal adaptation with the open structure

  • Primary and secondary cellular mirror, reducing the weight and faster thermal adaptation

  • 4 positions secondary mirror, manual or motoriZed rotation.

  • It is now possible to have 4 telescopes in one

Four Different Ports

Beautiful Engineering

Oversized Secondary

Precise Collimation

TELESCOPE TYPES

Prime Design

This telescope design uses no secondary but a focuser and camera on the front of the telescope instead, this allows maximum throughput of the telescope. Some benefits are:

  • Easier to balance; no load hanging off the side
  • Fast exposures
  • Guiding can be avoided

Standard Newtonian

A standard newtonian design with a secondary at the front of the telescope, but with a great twist. This design can be equipped with a rotating secondary with extreme precise motion. You can have:

  • A DSO imaging side with a high end CCD
  • A Fast DirectShow Camera for lunar/planetary/asteroid/satellite work
  • A Spectrograph
