FREE DELIVERY TO U.K. MAINLAND (surcharge may apply to distant areas, e.g. Scottish Highlands)


The new Skywatcher QUATTRO-10S 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.

2" DUAL-SPEED LINEAR POWER FOCUSER: The new linear power focuser utilises 4 precision ball bearings to support the drawtube and provide zero image shift and great stability while supporting a heavy eyepiece or camera. Moving the drawtube by the roller rather than a rack and pinion ensures precise adjusting, exceptionally smooth operation and great feel. 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.
