Quattro Imaging Newtonian’s are fast, large aperture astrographs,
delivering an optical system that excels at both imaging and visual
observation.
Fast, like, REALLY FAST
The Quattro Imaging Newtonian is one of the most affordable
telescopes with a focal length of 1200 mm and 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.
Solid and Precise Focusing
Whether you’re using the Esprit for imaging or visual use,
Sky-Watcher’s proprietary 2 inch dual-speed linear track 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!

"The Quattro's tube is lined with a set of nine internal baffle rings. Their main purpose is to cut down on stray light entering the telescope tube, helping to improve image contrast, but they also lend a bit of extra stability to the tube structure....The Quattro-8S is fitted with a Crayford-style focuser that performed well. It has tension adjustment, focus-lock and a 10:1 dual-speed fine focusing option, and also comes with a 2-inch fitting that has a T-thread on its external side. This allows a good connection to be made between scope and camera with the right adaptor ring....Visually, the Pleiades looked like diamonds hanging in space, with a hint of nebulosity visible around the brightest star Merope. The stars were generally crisp and sharp, with good colour on show. The scope is superb for imaging too, delivering shots that appeared to have higher contrast t han the other scopes on test."
BBC Sky At Night Magazine (Quattro-8S model)
BBC Sky at Night magazine group test winner scoring 89%
The superb Skywatcher Quattro-8S telescope OTA has beat all the opposition to win best in class in the November 2011 Sky at Night magazine. Designed for fast focal ratio photography. But also excellent for visual use. Superb value for money
