- 254 mm Newtonian reflector
- 1000 mm (f/4)
- Fully multi-coated borosilicate mirrors
- 2” dual-speed 10:1 linear power focuser
- 8×50 finderscope
- Tube rings with V-style dovetail bar
The new Sky-Watcher Quattro Imaging Newtonian with dual-speed focuser incorporates a superb mirror-set with two significant advantages over competing products. A 2″ dual-speed 10:1 ratio focuser is included for excellent focusing precision. Additionally, the tube length has been slightly shortened to optimize performance for prime-focus photography.
Fast, like, REALLY FAST
The Quattro Imaging Newtonian is one of the most affordable telescopes with a f/4 focal ratio. This astrograph is capable of producing an exposure 6x faster than the average 8” f/10 Schmidt Cassegrain telescope! Even pricey refractors have trouble reaching a focal ratio this fast. Using a faster optical tube will shorten the exposure time on your camera, giving you more time to photograph nebulae, clusters and other deep sky objects.
Built to Perfection
Like all Sky-Watcher reflectors, our Quattro Imaging Newtonian features borosilicate mirrors with a quartz overcoat, producing 94% reflectivity. The optical system uses an oversized secondary mirror, providing greater illumination for DSLRs and CCDs using full-frame sensors. The optical tube is constructed with rolled steel, and features Sky-Watcher’s signature glossy metal-flake Black Diamond finish on the exterior. The interior of the optical tube uses knife edge baffling* to absorb any stray light.
* To improve cooling, larger 12” model does not feature baffling
Solid and Precise Focusing
Whether you’re using the Esprit for imaging or visual use, Sky-Watcher’s proprietary 2.7” and 3.4” dual-speed focuser provides precise 10:1 rack-and-pinion focusing with zero image shift. The focusers are rotatable, allowing astrophotographers to easily frame their image. The large aperture focuser includes millimeter markings to assist with quick and accurate focusing.
Jack of all Trades
Did you know the Quattro Imaging Newtonian is also an excellent visual observation instrument? Although this optical tube is excellent for deep sky imaging, the wide aperture and short focal length produces a bright and vivid viewing experience. If you’re looking for one optical tube to use for both visual and photography, then look no further than the Quattro!
