Your cart is empty. 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 any f/10 optical tube.
Even pricey refractors have trouble reaching a focal ratio this fast. Using a faster optical tube
will shorten the exposure time, giving you more time to photograph nebulae, clusters, and other
deep sky objects.
Like all Sky-Watcher reflectors, our Quattro Imaging Newtonian features aluminum-
coated 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 metal-flake Black Diamond finish on the exterior. The interior of the optical
tube uses knife-edge baffles to absorb any stray light from ruining your images.
As customary with all Sky-Watcher telescopes, a boat-load of accessories are bundled
with the optical tube. First is a 2-inch dual-speed 10:1 focuser with included 1.25-inch eyepiece
adapter, which provides flexibility for either 1.25-inch or 2-inch eyepieces. Also included are
tube rings and a V-style dovetail plate, as well as a 9x50 finderscope. For photographers
looking to create a flat field and eliminate vignetting, an optional coma corrector is available
separately. Parabolic mirrors normally produce some aberrations around the edge of the field of
view (coma), so this corrector is highly recommended for users with large imaging sensors and full-frame DSLRs.

This was my first newtonian for astrophotography and I was not disappointed. The attached photos were captured before taking the time to collimate (I did use the coma corrector purchased separately)

Arrived within 2 days of purchase shocking however did arrive with some superficial tears and indents on the box however scope was unscathed. I'd say by the hair of it's chinny chin chin. After a time with it I'm realizing the scope is not completely done being built. Thay are still using 1980s technology and charging 2024 prices for it. I do not recommend this scope for anyone that wants to push and play astronomy. I will need to flock it, replace the veins and paint the clips.

Overall score 4/5 Stars. 3/5 for Shipping. This rating is purely based on it's arrival. I love this telescope and I'm glad it arrived intact. It was delivered to me in a month's wait. Shipped from China and went directly to Celestron in NJ. Then shipped to out to Amazon distribution center in CA for the final ship leg over water to HI which only took 1 week. I had opted for the repackaging not to reveal contents of the item and also to for the extra protection. But that didn't happen. Maybe because the of the large box it comes with to begin with. The box arrived like it went through a gorilla inspection. The taped ends were half undone and there was a gaping hole big enough to put my fist through. When I first saw it I literally cringed inside. But to my surprise the telescope was unharmed. The telescope sits in a acrylic stiff foam cradle spaced about 3 inches from the outer box layer. All contents accessories were unharmed. Collimation was spot on but the back primary lockdown collimation screws were loose. I tightened them and it didn't change the collimation. I would give it a 5/5 rating but for the poor packaging and unwillingness to protect a costly item like this it deserves no more than a 3. And if it arrived damaged it would be a 2. The telescope itself is a 5! Overall score is a 4.

Box and packaging okay, but there is a large dent in the optical tube.
