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 microprocessor-controlled,precise
celestial-object tracking, all in a nicely styled, highly portable
Improvements to this model include a new fork mount with
dual-axis drive system. 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 push button tracking
in altazimuth mode; moderate, 0.75degrees per second for image
centering in the viewfinder or for terrestrial tracking; and fast, 5
degrees per second for fast scanning across the sky.
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 40hours 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 multi-coatings
on all optical surfaces to maximize light transmission through the
corrector lens reluctance 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.
