The Sky-Watcher Quattro 150P reflecting telescope was designed and built to provide astrophotographers a high quality imaging experience. The fast f/3.45 aperture helps reduce exposure times, while the thermally-stable borosilicate glass used as the reflector helps your shots stay in focus for longer.
Sky-Watcher Quattro 150P Astrophotography Reflector
Included as part of this astrophotography Newtonian reflector telescope is a 2" dual-speed Crayford power focuser. This high-end focuser utilizes ball bearings to maintain perfect drawtube alignment, ensuring smooth focusing and zero image shift, even when supporting heavy imaging payloads. The Sky-Watcher Quattro 150P's Crayford focuser offers smoothness and accuracy that traditional rack and pinion focusers can't match. The dual-focuser setup features a high-speed main knob for primary focusing, and a second focus knob with 10:1 focus speed reduction for super fine focus adjustments that will please even the pickiest astrophotographers.
Sky-Watcher Quattro 150P Low-Expansion Borosilicate Glass
High accuracy focusers are of little help when your telescope is constantly expanding and contracting due to changes in temperature. That's why the Sky-Watcher Quattro 150P uses low-expansion borosilicate glass in its primary mirror. This very stable glass will shorten cool down times and help keep objects in crisp focus for the long exposure times required in astrophotography. In order to let as much light as possible hit the primary mirror, the secondary mirror on the Quattro 150P uses 0.5mm mirror support brackets. These super thin supports significantly increase the amount of light able to reach your camera, reducing exposure times and increasing clarity.
