  • The Sky-Watcher Quattro Imaging Newtonian telescope with dual speed focuser includes a premium mirror-set and a 2" dual-speed 10:1 ratio focuser for precision focusing for optimal performance.

  • The SkyWatcher Quattro 10 is a fast f/4 Newtonian with extra features that make it an excellent OTA for imaging as well as wide field visual observations with the addition of its dedicated coma corrector (sold separately).

  • This 8” SkyWatcher Quattro Imaging Newtonian has an 1000mm focal length for a focal ratio of f/4.  This moderately fast optical design strikes an balance between optimal optical performance while allowing for shorter exposure times. The parabolic mirrors are ground from borosilicate glass and fully multi-coated for bright, sharp images.

  • The SkyWatcher Quattro 8” comes with a 2” dual speed 10:1 linear power focuser. 10:1 dual speed focus allows you to make larger adjustments to focus in the normal manner, and then use the fine focus knob for smaller adjustments to allow for precision focusing and sharp images.

  • Includes a straight-through 8x50 finder and bracket as well as a tube ring set with a Vixen-style dovetail bar for mounting on a wide variety of equatorial mounts.

  • For visual use, we recommend the SkyWatcher Quattro coma corrector. (optional)

Product Description

Sky-Watcher - 10” Quattro Imaging Newtonian OTA - S11220

This 10” Newtonian reflector optical tube from Sky-Watcher USA has an 1000 mm focal length and a fast f/4 focal ratio. The parabolic mirrors are ground from borosilicate glass and fully multi-coated for bright, sharp images. As well as precise optics, the focuser is one of the most important components of the telescope system, and that is especially true when imaging. The Sky-Watcher 10” Quattro comes with a 2” dual speed 10:1 linear focuser. 10:1 dual speed focus allows you to make larger adjustments to focus in the normal manner, and then use the fine focus knob for even more precise images.

The Sky-Watcher Quattro Imaging Newtonian comes with a straight-through 8 x 50 finder and bracket as well as a tube ring set with a D-Style (Losmandy) dovetail bar for mounting on a wide variety of equatorial mounts. The Quattro Coma Corrector is available optionally. It will correct for coma around the outer edges of the primary mirror (not un-common with fast Newtonians). This correction is desirable for visual use as well as when you want crisp, pin-point results to the edges of the field when deep-sky imaging.
