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.
The ETX line is a good line of amateur scopes. All ETX models are not equal, by far! The ETX 60, 70,80 are refractor types and built cheaper than the larger objective ETX 90, 105, 125 models. The latter three are Muskatov design and much better optically and made in the USA. Still they suffer from drive mechanism failures of different sorts. Most common failure is the broken Declination locking knob since it's plastic and snaps. Fix is easy if you know what you are doing to repair it. Worse yet is when the 4 wires that run through the partially hollow RA locking bolt. The wires fray or sever and the entire scope base needs disassembled and depth of repair depends how badly the wires are damaged. That's also a good time to check for broken gear teeth, split screw anchors in the base assembly, end play in the worm drive, and so on. All those issues will cause bad tracking or inaccurate auto-star finder. Mine had all of those issues and has taken mush time to repair albeit I did it myself, made improvements so it wouldn't happen again, and saved spending more $$ on a scope that should have been designed better from the start! People who pay several hundred $$ or more for these used on eBay are crazy! Only do that if it's in pristine, guaranteed working condition. Otherwise pay $150 and fix it yourself to end up with a nice little performer. The views through the ETX 90, 105, 125 are so much better than the smaller 60/70/80 models. I dumped my smaller models quickly after having the USA made one. Meade tripods make a big difference in stability. The cheaper aluminum ones are fair to lousy. The heavy chromed leg ones are better. The focus mechanisms all suck for the most part but mods can be made to the 90/105/125 models that perform nicer and more tolerable. Keep in mind that these are basically grab'n-go scopes. They are not research grade at all yet the USA models give nice views. Just don't spend tons of $$$ like some of the sellers asking $1200 or more for their used scope. Instead, put that amount of money into a Meade LX or Celestron C8 or similar that will surpass these things.

Mount Type Altazimuth
I have been an amateur star gazer since I was a young boy. My father taught me about many of the constellations. About 4 years ago I bought a Meade 114 EQ reflector scope and had fun looking at Jupiter, the Moon and star clusters like Pleiades (M45). Started searching and bidding on eBay for a new, telescope and got a great deal on the ETX 90EC. It came with the top of the line Meade tripod, 2 lenses and the 497 upgrade Autostar controller. It was 10 years old but in mint condition. I started looking at Jupiter and the Moon with great success. The auto tracking and Go To were working great. So then I decided to purchase the Meade 4000 series Super Plossl lens set with color & moon filters, then I bought a 3 piece set of Nebula filters. I then started looking at Deep Sky Objects and was finding them as little fuzzy blobs, still very cool. Now I also own an ETX70 & ETX125 models purchased on eBay. Good luck and as always…Clear Nights!
If you are an absolute beginning astronomer, my strong recommendation is buy a NEW scope. I found the big risk is not the optics but the teeth of the two drive motors are damaged or striped. Users must try to aim the scope by manually twisting the fork assembly instead of using the controller buttons. If I took a wild guess, I would say the fork assembly actually represents well over 50% of the total value of the package. Do not get hypnotized by the beautiful blue tube and mirror when considering a bid. I have never seen a new unit right out of the box in operation but if the unit I purchased was meticulously maintained as stated, the gears and motors are of very poor quality (not the optics). The backlash and grinding sounds are very disconcerting. More like what I would expect from a $100 Fisher-Price dinosaur toy.
