High-end Ritchey-Chrétien truss telescope: Full Carbon Lightweight

The truss frame is entirely built with mono directional high module carbon fiber tubes. The connection rings are fabricated with 6 mm high module carbon fiber plates.

The primary mirror cell is a true technological jewel: 100% structural carbon fiber construction, 18 points computer optimized mechanical cushion, and zero thermal expansion. It is fully tiltable through 3 bolts placed on the telescope's back plane. The cell's maximum deformations under the highest mechanical stress configuration (tube pointing at the zenith) are less than 0.03 mm.

With the secondary mirror assembly we created a mechanism of unmatched reliability, stability and lightness. The fully tiltable cell is fixed to a very sturdy carbon fiber mechanism.

The aluminium dovetail is always machined according to match the specific mount on which the instrument will be installed.

The back plane on all standard models is made of a solid 8 mm thick, high module carbon fiber plate. It hosts a tiltable ring ready to accept the crayford focuser of your choice.

We suggest an optional adapter that can be receive the 2,5" Feathertouch focuser.
