Product Details

  • The Sky-Watcher Quattro 8" (205 mm) Imaging Newtonian OTA is a great optical tube assembly for either visual astronomy or astro-imaging work. This fast 8-inch 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 2-inch 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.

    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 8-inch (205 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.

    When the OTA is assembled with its accessories, the total weight of this product (less its packaging) is 21-pounds.

SkyWatcher 8" Quattro 200P - First impressions

I haven't had the opportunity to observe with scope yet. I'll list my first impressions. The box it came in was a little dented in places when it arrived. Fortunately, everything inside was fairly well padded and intact. First thing I noticed after assembly and installing on my mount was that it was completely out of collimation. I had to adjust the secondary and primary mirrors using a laser collimator. I did it initially with a Cheshire, but it wasn't as close as I needed it. I learned a lot in the process of collimating both with the Cheshire and the laser. It comes with the tube rings and a finder scope. The finder scope is decent, but there are probably better aftermarket ones. The primary scope itself is well built. There's only been one thing that gives me pause. The focuser is a little sloppy even with the fine adjustment. The focuser has 2 locking bolts that are opposite each other which makes me wonder why one wouldn't do until I tried using only one. It'll slip when you attempt to turn the focuser. I'm already looking into an aftermarket focuser. Given the price of the scope, I was hoping for a slighter better focuser. My first choice (Orion 8" Astrograph) had a wait time of multiple months, so I had to settle on this one. That scope is $150 cheaper than this one and I think comparable in build quality. Overall, I'm happy with the scope, but it was my second choice.
