Skywatcher Quattro 10CF f/4 Carbon Fibre Newtonian: £851.00

250mm f/4 Dual Speed Parabolic Imaging Newtonian OTA

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.

CARBON FIBRE TUBE: Carbon fibre is a strong and lightweight material and has much better thermal stability compared to a steel tube. 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 and long exposure images will stay clear and in focus.

2" DUAL-SPEED LINEAR POWER FOCUSER: 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: Features paraboloidal primary mirrors made of low thermal expansion Pyrex glass resulting in substantially shorter cooling-down times.
