The new Sky-Watcher Quattro-10S Steel Tube with fast f/4 focal ratio, have been specially designed for high quality astrophotography with short exposure times. The tube interior has knife-edge ray-traced baffles.
2" DUAL-SPEED LINEAR POWER FOCUSER:
The new linear power focuser utilizes 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.
PYREX MIRRORS:
The primary mirror is made of low thermal expansion Pyrex glass resulting in substantially shorter cooling-down times.
