Sky-Watcher Quattro 8" F/4 Imaging Newtonian OTA
SkyWatcher 8” Quattro Imaging Newtonian
The SkyWatcher Quattro 8 is a fast f/4 Newtonian with extra features that make it a really nice OTA for imaging as well as visual observation.
This 8” SkyWatcher Quattro f4 Imaging Newtonian has an 800 mm focal length. The parabolic mirrors are ground from borosilicate glass and fully multi-coated for bright, sharp images.
Besides the optics, the focuser is one of the most important components of the telescope system, and that is especially true when imaging. 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 tweaks that are so critical to producing a sharp final image.
The SkyWatcher Quattro f4 Imaging Newtonian comes with a straight-through 8 x 50 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. The Quattro Coma Corrector is available optionally. It will correct for coma around the outer edges of the mirror that are typical of fast Newtonians. This correction is desirable when you want to shoot to the edges of the field for some deep-sky imaging work.
