The Skywatcher Quattro series are premium quality imaging Newtonians with a wide field of illumination and fast f4 focal-ratios.

CARBON FIBRE TUBE: Carbon fibre is a strong and lightweight material with better thermal stability than steel. This is especially important for astro-photographers dealing with long exposure times. Imaging telescopes made of less thermally stable material can deviate from optimum focus after long time exposures. With a carbon fibre tube, it can remain in focus for a longer period of time.

2" DUAL-SPEED LINEAR POWER FOCUSER: The new linear power focuser utilises four precision ball-bearings to support the drawtube for excellent stability and zero image shift while supporting a heavy imaging camera and accessories. Moving the drawtube using a roller rather than a rack and pinion ensures an exceptionally smooth and precise focus adjustment. The dual-speed feature has a second focus knob with a 10:1 speed reduction for super-fine adjustments.

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

NB: Fast Newtonians are best suited to experienced astronomers. They require precise collimation and a Coma Corrector to reach their full potential. If you are unsure whether one will suit your requirements please email or phone to discuss before placing an order
