250 mm Hi End Ritchey-Chrétien truss telescope.
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 cut with water-jet.
The primary mirror cell is a true technological jewel: 100% structural carbon fiber construction, 9 points computer optimized mechanical cushion, and zero thermal expansion. 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 sturdy carbon fiber mechanism.
The dovetails are engineered with a proprietary hybrid Aluminium-Carbon fiber construction (optional Titanium/Carbon). This type of design minimizes torsion deformation and structural misalignment under every pointing orientation. In comparison with traditional CNC aluminium dovetails, the deformations are reduced by a factor 40.
The back plane on all standard models is made of a solid, high module carbon fiber plate. It can host up to a 3,5" Feathertouch focuser with ca. 10 kg of equipment attached.The optional Titanium/Carbon design ensures an even higher strength.
