    Product Description

    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.

    Awesome scope!
    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)

    4.0 out of 5 stars It comes from China so shipping takes a month.
    Reviewed in the United States on May 13, 2020
    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.

    2.0 out of 5 stars Cheap Build Need to Replace Parts and Add Fan
    Reviewed in the United States on March 28, 2023
    I purchased the Sky-Watcher Quattro 200P through a local retailer for the purpose of complimenting by Celestron 8 SCT for wide(r) field astrophotography. I am very disappointed with Sky-Watcher - in general - and, particularly with this scope. Frankly, I think the build and components are seriously lacking in quality.

    If you're serious about astrophotography, you cannot have weak links in the process, especially where you dedicate so much time and energy to taking subframes.

    For starters, the focuser needs to be replaced. As a two speed Crayford, the fine adjustment would work, but the course adjustment would "click" and have a gritty feeling. In all, the machining of the Sky-Watcher parts is not precise and buried in a heavy coat of paint. I replaced the focuser with an Omegon at the cost of around $400, including tax and shipping.

    Next - and more importantly - the primary mirror was not seated properly. If you take the primary mirror cell off and rotate it, you will see the mirror flopping back and forth by about 1/8th of an inch (at least in my copy). Of course, without being re-seated and secured, this will never hold collimation.

    Third, this is the only imaging Newtonian in this class that does not come with a fan. For imaging, bringing the mirror to within 3 degrees Celsius of ambient air temperature is necessary to reduce tube currents that effect imagining. So, I built a custom fan assembly, as pictured and will run it off an ASIAIR. As to mirror retention of heat, it is not aperture, but thickness of the mirror. This mirror is 25.5 mm thick.

    Please note that the GSO primary mirror holder with the fan will not accommodate the primary mirror on this scope. The Quattro mirror is slightly too large.

    Fourth, while this is rather common with consumer class Newtonians, the secondary is merely adhered (seemingly with double sided tape) to the secondary post. ("Post" means I don't know what to call it as it's not a holder.) I have read accounts online where the secondary mirror has fallen off over time. Accordingly, it was necessary to find a secondary mirror holder of appropriate length and buy a new secondary rather than chisel the original mirror off the post. The cost for both components was around $160.

    The finder scope that comes with the Quattro is a plastic toy and should be discarded.

    In all, I am very disappointed with this scope - especially after hearing how great the thing was supposed to be. I'm roughly $630 out of pocket to get my $830 (over-priced) "imaging Newtonian" in condition to be useable. ($400 focuser, $160 for a secondary and holder and roughly $70 in components and a long day of labor to build a fan.)

    Had I known that this would be the build quality, I would have saved my money for a more serious instrument. The Sky-Watcher Quattro is unfortunately an example of a cheap off-shore product put into the stream of commerce.
