254mm f/4 Dual-Speed Parabolic Imaging Newtonians -   The new QUATTRO series with their fast f/4 focal ratios, have been specially designed for high quality astrophotography with short exposure times. They are of course also fine telescopes for visual observations.


Tube interiors have knife-edge ray traced baffles.

This model is the QUATTRO-10S with Steel Tube


2" DUAL-SPEED LINEAR POWER FOCUSER: The new linear power focuser utilises 4 precision ball bearings to support the drawtube and provide great stability and zero image shift while supporting a heavy eyepiece or camera. Moving the drawtubeby the roller rather than a rack and pinion ensures exceptionally smooth operation, great feel and precise adjustability. The dual-speed feature has a second focus knob that has a 10:1 speed reduction to provide the super-fine adjustments even the most demanding users can appreciate.


PYREX MIRRORS: Both models feature paraboloidal primary mirrors made of low thermal expansion Pyrex glass resulting in substantially shorter cooling-down times.

  • Highest Practical Power (Potential) x508
  • Diameter of Primary Mirror 254mm
  • Telescope Focal Length 1000mm (f/4)
