This 12” Newtonian reflector optical tube from Sky-Watcher USA has an 1200 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 12” 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.

Product Description

Sky-Watcher 12" Quattro Imaging Newtonian OTA

This 12” Newtonian reflector optical tube from Sky-Watcher USA has an 1200 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 12” 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.
