Sky-Watcher Quattro-10S 250mm f/4 Dual-Speed Parabolic Imaging Newtonian

The new Sky-Watcher 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.

Please note that the image shown is for the Carbon Fibre Version. The Steel tube differs slightly in appearance.

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