Sky-Watcher Quattro-8S F4 Imaging Newtonian OTA (10238)
Original price was: $383.00.$99.99Current price is: $99.99.
The SkyWatcher 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. The 8 inch Quattro tube interior has knife edge ray-traced baffles. 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. The Quattro-8S features a paraboloidal primary mirror made of low thermal expansion Pyrex glass resulting in substantially shorter cooling-down times. Comes complete with 9×50 finderscope, tube rings and dovetail bar. Please note no eyepieces are supplied.
