|The Meade ETX-90EC telescope is a portable observatory designed for both astronomers and amateur stargazers. With 90mm Maksutov-Cassegrain optics, built-in flip mirror mechanism, and fast and easy alignment procedure, this telescope allows users to easily locate moon craters, cloud belts on Jupiter, Saturn's rings, and more. With a 1250 mm focal length and a f/13.8 focal ratio, celestial observations have clarity and detail. The AutoStar Suite Planetarium software allows total computer control of the mount and telescope, and access to a database of over 30,000 celestial objects. Weight is less than ten pounds, so the telescope is lightweight and easy to transport.|

Meade finally brings a serious telescope into the casual consumer price range. The ETX-90EC Astro offers extraordinary optics at an affordable price. It combines a high-resolution optical design and diffraction-limited imaging with micro processor-controlled, precise celestial-object tracking, all in a nicely styled, highly portable package.
The ETX-90EC also includes high torque DC motors on both telescope axes, permitting electronic operation from the hand-held controller. This push-button electronic controller has four dual-axis drive speeds: slow, 8x for image centering at high power; medium, 32x for image centering at lower power or for pushbutton tracking in altazimuth mode; moderate, 0.75 degrees per second for image centering in the viewfinder or for terrestrial tracking; and fast, 5 degrees per second for fast scanning across the sky.
The Meade ETX-90EC is specially designed to be portable and used in the field. It offers cordless operation, allowing you to use the telescope's dual-axis drive system for more than 40 hours on eight AA batteries. At approximately 8 pounds and 15 inches in length, it packs a lot of power into a compact unit.
TheETX-90EC uses a 90mm Maksutov-Cassegrain optical design, and Meade actually warranties the optics of the ETX-90EC "to equal or exceed the optical performance and resolution of any Maksutov optics of similar aperture ever manufactured at any price." The ETX-Series optics offer superb contrast, image brightness, and resolution; Meade claims the telescope consistently outperforms many instruments of larger apertures. Meade also uses EMC super multicoating on all optical surfaces to maximize light transmission through the corrector lens and reflectance from the primary and secondary mirrors. The flip-mirror system allows for 90-degree observation of land and sky objects,straight-through observation using the optional #932 45-degreeErecting Prism, or photo-ready imaging using the optional #64T-Adapter and your own 35mm camera.
Overall, the Meade ETX-90EC is a fine piece of craftsmanship at a surprisingly affordable price. For those of us who spent our childhood peering through old-style consumer telescopes, using the ETX-90EC is like getting time in the Palomar Observatory. From shifting cloud belts on Saturn to the glowing filaments of the Orion Nebula, this instrument lets you observe the heavens in extraordinary detail.
