Skywatcher Quattro 200P Imaging Newtonian 8"

Sky-Watcher's 8" f/3.9 Quattro Imaging Newtonian Telescope is specifically engineered for astrophotography and astro-imaging performance. Its shortened 800mm focal length produces a fast f/3.9 focal ratio to reduce the exposure times required for capturing detailed images of the Moon, planets, and deep-sky objects. To further boost performance, borosilicate mirrors with a low coefficient of thermal expansion to reduce the effects of expansion/contraction when the temperature fluctuates. This helps limit distortion that can occur when moving the OTA from indoors to outdoors. The entire optical system is fully multicoated to increase the reflectivity of all surfaces to produce brighter and sharper images.

For imaging and visual use, the ability to achieve tack-sharp focus is critical, so Sky-Watcher outfitted the Quattro with a large 2" Crayford-style focuser. This design uses a steel rod held tightly against the focus tube under tension. Using this toothless friction system eliminates backlash and enables ultrafine precision focusing. A large coarse-focus wheel quickly brings subjects into rough focus, and the 10:1 fine-focus allows you to precisely focus it without the risk of losing it as soon as the knob is released. Having the ability to use larger 2" accessories and eyepieces provides an immersive experience during observation sessions and the ability to use larger sensors for capturing images.

The Quattro is offered here without a mount or tripod for users who have a solid observation platform. Its cradle ring assembly clamps over the OTA so you can position it for balancing when mounted and place the eyepiece precisely for more comfortable observations. It also allows adjustment of the entire rig so you can avoid interference with other equipment and accessories. A dovetail plate on the bottom of the cradle ring assembly makes this OTA compatible with any Vixen-style saddle.
