Better astrophotos that help you discover the sky in a new way. What is it that drives astrophotographers time and again? It is the fascination of depicting the sky in its most beautiful colours and shapes. With this apochromat, you can do just that. The premium ED glass and a colour-pure image make for enjoyable observations with fine details that would not be possible with basic optics. Rediscover the sky. Why these optics reveal more details No more images without contrast. This apochromat shows what is really possible: pure-colour and high-contrast observations and astrophotos. The key is a sophisticated optical design with premium ED glass for a crystal-clear image. Compared to most mirror systems, the better-defined optics allow you to see more and finer details when observing the planets, for example. All surfaces of the lens elements are treated with an effective multi-coating to prevent reflections. Enjoy memorable observations and shots. 2.5 focuser with gearing and ball bearings This 2.5 geared focuser is a small spatial miracle, and large enough that no shading occurs. An ingenious hybrid technology comprising a Crayford focuser and a gear wheel makes it particularly strong and suitable for accessories weighing up to 4kg. The ball bearings provide for smooth focusing, allowing you to easily find the perfect focus. A 1:10 reduction gearing makes precise focusing a breeze. Astrophotographers around the world value precisely these features. 360° rotation for framing the perfect photo. You found the object and focused on it, but with the wrong orientation? Save yourself the trouble of having to start over again at night to align an elongated object with the sensor. This is ea. |

The Quattro Imaging Newtonian is one of the most affordable telescopes with a f/4 focalratio. 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 tubewill shorten the exposure time, giving you more time to photograph nebulae, clusters, and otherdeep sky objects.Like all Sky-Watcher reflectors, our Quattro Imaging Newtonian features aluminum-coated borosilicate mirrors with a quartz overcoat, producing 94% reflectivity. The opticalsystem uses an oversized secondary mirror, providing greater illumination for DSLRs and CCDsusing 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 opticaltube 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 bundledwith the optical tube. First is a 2-inch dual-speed 10:1 focuser with included 1.25-inch eyepieceadapter, which provides flexibility for either 1.25-inch or 2-inch eyepieces. Also included aretube rings and a V-style dovetail plate, as well as a 9x50 finderscope. For photographerslooking to create a flat field and eliminate vignetting, an optional coma corrector is availableseparately. Parabolic mirrors normally produce some aberrations around the edge of the field ofview (coma), so this corrector is highly recommended for users with large imaging sensors and full-frame DSLRs. |
