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. Quattro 8″ tube interiors have knife-edge ray traced baffles. 2″ DUAL-SPEED LINEAR POWER FOCUSER (both models): 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 MIRROR: Feature paraboloidal primary mirror made of low thermal expansion Pyrex glass resulting in substantially shorter cooling-down times. (Please note the Quattro-200P was formerly named Quattro-8S)
