(More customer reviews)I am truly an amateur astronomer. My childhood was peppered with dime-store telescopes that showed me a new blurry world. When I got the EXT-90EC I expected little more than a brighter blur. To my surprise and delight I was wrong. Out of the box, in bad lighting conditions, surrounded by trees, I saw some of the most breath-taking images of the moon. In fact, I spent the next six hours observing the moon. I saw craters in detail. I even saw some craters within craters. I did venture to a bright star I saw in the sky. It turned out to be Jupiter. It was a highly recognizable Jupiter. Not another dot in the sky. I could see three of Jupiter's moons in orbit. I couldn't even make out Jupiter's moons with the naked eye.
I tried the telescope during the day for terrestrial viewing. Once again I was pleasantly surprised! The local river area came alive with wildlife. The photographic possibilities are endless!
I purchased the #883 Deluxe field tripod, #932 45 Degree Erecting Prism, #497 Autostar controller, and the #774 hard case with the telescope. I highly recommend you do the same. They all add to the total experience. The tripod is a must for both astrological and terrestrial viewing. The 45 Degree Erecting Prism is needed for terrestrial viewing. If you don't use it, your images will be inverted. The autostar, once aligned, will position the telescope to any viewable object, and then continue to track it. The case is a convenience and insurance policy.

Meade finally brings a serious telescope into thecasual-consumer price range. The ETX-90EC Astro offers extraordinaryoptics at an affordable price. It combines a high-resolution opticaldesign and diffraction-limited imaging with microprocessor-controlled,precise celestial-object tracking, all in a nicely styled, highlyportable package.
Improvements to this model include a new forkmount with dual-axis drive system. The ETX-90EC also includes hightorque DC motors on both telescope axes, permitting electronicoperation from the hand-held controller. This push-button electroniccontroller has four dual-axis drive speeds: slow, 8x for imagecentering at high power; medium, 32x for image centering at lowerpower or for pushbutton tracking in altazimuth mode; moderate, 0.75degrees per second for image centering in the viewfinder or forterrestrial tracking; and fast, 5 degrees per second for fast scanningacross the sky.
The Meade ETX-90EC is specially designed to beportable and used in the field. It offers cordless operation, allowingyou to use the telescope's dual-axis drive system for more than 40hours on eight AA batteries. At approximately 8 pounds and 15 inchesin length, it packs a lot of power into a compact unit.
TheETX-90EC uses a 90mm Maksutov-Cassegrain optical design, and Meadeactually warranties the optics of the ETX-90EC "to equal or exceed theoptical performance and resolution of any Maksutov optics of similaraperture ever manufactured at any price." The ETX-Series optics offersuperb contrast, image brightness, and resolution; Meade claims thetelescope consistently outperforms many instruments of largerapertures. Meade also uses EMC super multicoatings on all opticalsurfaces to maximize light transmission through the corrector lens andreflectance from the primary and secondary mirrors. The flip-mirrorsystem 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 isa fine piece of craftsmanship at a surprisingly affordable price. Forthose of us who spent our childhood peering through old-style consumertelescopes, using the ETX-90EC is like getting time in the PalomarObservatory. From shifting cloud belts on Saturn to the glowingfilaments of the Orion Nebula, this instrument lets you observe theheavens in extraordinary detail.
