Sky-Watcher Quattro-10S f/4 250mm Dual-Speed Imaging Newtonian (steel tube) - 10239
The 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. 10" Quattro 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 drawtube by 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: Features paraboloidal primary mirror made of low thermal expansion Pyrex glass resulting in substantially shorter cooling-down times.
(Please note the Quattro-250P was previously named Quattro-10S)
