Sky-Watcher Quattro 12" Imaging Newtonian OTA

The Sky-Watcher Quattro 12" (305 mm) Imaging Newtonian OTA is a great optical tube assembly for either visual astronomy or astro-imaging work. This fast 12" f/4 Newtonian telescope has a superb mirror set, allowing you to see sharp, high contrast images of celestial objects. Additionally, the tube length has been slightly shortened to optimize performance for doing prime-focus photography. A 3" dual speed 10:1 ratio focuser is included for precision focusing adjustments, and an 8x50 finderscope will provide bright views when you're hunting down your favorite deep-sky object. This large aperture 12" Newtonian telescope is a smart choice for upgrading from a smaller mid level scope to a more advanced scope for serious observations and astroimaging.

Sky-Watcher has designed a custom coma corrector for those astro-imagers with larger imaging sensors. The optional Quattro Coma Corrector will improve both visual and photographic performance by correcting for coma around the edges of the field of view, a normal aberration found in optical systems using parabolic mirrors, such as a Newtonian telescope.

Because this Sky-Watcher Quattro 12" (305 mm) Imaging Newtonian OTA incorporates significant improvements over competing fast Newtonians, you will be assured of rewarding views of many celestial objects and also achieve good image results when doing astroimaging.

Questions & Answers

Product Questions

What is the weight of the OTA?
What is the overall length of the OTA?
According to Todd R. this OTA weighs 57 lbs. Sky-Watchers best EQ mount (Sky-Watcher EQ6) only has a 40 pound payload capacity making it unusable for this OTA. (What were they thinking?!)

So which mount(s) should we be looking at to use this OTA for viewing/astrophotography?
Can you tell me if the OTA tube is steel or carbon fiber, please?
