Meade ETX90AT Telescope w/884 Tripod and Software Short Description

Super popular Meade ETX-90AT Astronomical Telescope is one of the best Maksutov-Cassegrain 90mm telescopes available on the market today: For the casual or beginning observer the Meade ETX-90AT telescope may be all the telescope ever required. Or, for the advanced astronomer who already owns a larger instrument, the Meade ETX-90AT is the perfect ultra portable, diffraction-limited field telescope. Observe the continually changing cloud-belt patterns on the surface of the planet Jupiter; shadows cast on to Jupiter as one of its four principal satellites transits the planet’s disc; the magnificent ring system and satellites of Saturn as well as dusky markings and the ring-shadow on the surface of Saturn; Moon craters by the hundred, plus lunar rilles, mountain ranges, and fault lines, all visible in brilliant, high-resolution, high-contrast detail; the variable phases of the planets Mercury and Venus; prominent features on the surface of Mars. With Meade ETX-90AT in deep-space the motivated observer will find it difficult to exhaust the quantity of visible phenomena: the incandescent filamentary structure of the Orion Nebula; the elliptical luminosity of the Andromeda Galaxy with its brilliant nucleus; the shining orb of the Hercules globular cluster with many of its outermost stars resolvable. These are only a few of the literally thousands of celestial objects within the view of the Meade ETX-90AT telescope. Star catalogs list innumerable double and multiple star systems, variable stars, open star clusters, globular clusters, diffuse nebulosities, planetary nebulae, and spiral galaxies within the grasp of the instrument. The optional Autostar Computer Controller can locate all of these objects automatically, in seconds.Amazon.com Product Description This telescope includes a free Autostar computer controller and deluxe field tripod with this ETX-90EC–a value of 9. And with the ETX-90EC, Meade brings a serious telescope into the price range of the casual consumer. 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 package. The Autostar controller turns the ETX-90EC into an automatic celestial-object locating system.


Catadioptrics
    This is a catadioptric telescope. Catadioptrics use an ingenious combination of mirrors and lenses to “fold” the light path into a remarkably compact tube. This type of design–which includes Schmidt-Cassegrain and Maksutov-Cassegrain telescopes–offers good value even while it scores high on the techno-geek meter.

    • Just plug the Autostar into the telescope’s HBX port in place of the standard-equipment electronic controller, do a quick telescope alignment, and you’re ready to observe any object in the Autostar’s 30,000-object database.

    The ETX-90EC also includes high-torque DC motors on both telescope axes, permitting electronic operation from the handheld controller. This pushbutton 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.

    The ETX-90EC uses a 90mm Maksutov-Cassegrain optical design. Meade also uses EMC super-multicoatings 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 45-degree erecting prism, or photo-ready imaging using the optional T-adapter and your own 35mm camera.

    The Nuts and Bolts

    1. Eyepiece
    2. Viewfinder
    3. Eyepiece Holder Thumbscrew – Tightens the eyepiece in place.
    4. 90° Eyepiece Holder – Holds the eyepiece upright for easy viewing.
    5. Optical Tube – The main optical component that gathers the light from distant objects and brings this light to a focus for examination with the eyepiece.
    6. Vertical Lock – Controls the manual vertical movement of the telescope.
    7. Fork Arms – Hold the optical tube in place.
    8. Focus Knob – Moves the telescope’s optical tube in a finely-controlled motion to achieve precise image focus.
    9. Horizontal Lock – Controls the manual horizontal rotation of the telescope.

    10. Computer Control Panel

    • A. ON/OFF Switch.
    • B. Auxiliary Ports – Provide connection for current and future Meade accessories.
    • C. Handbox (HBX) Port – for the Electronic Controller or the optional Autostar handbox.
    • D. The 12v connector, designed to accept an external power supply such as the optional AC Adapter or Power Cord.
    • E. LED power indicator light.

    11. Base Housing – Supports the telescope for placement on a flat, level surface, such as a tabletop or optional tripod.
    12. Holes for Optional Tripod – See your tripod’s instruction sheet for mounting information.
    13. Right Ascension (R.A.) Setting Circle.
    14. Flip-Mirror and Flip-Mirror Control Knobs – ETX telescopes include an internal mirror. With the flipmirror control in the “up” position, light is diverted to the eyepiece. With the flipmirror control in the “down” position, as shown in Fig. 2b, light proceeds straight out the photo port for photography.
    15. Photo Port – Attach any 35mm camera with a removable lens to this port using an optional adapter.
    16. Declination Setting Circle (on left fork arm).
    17. Viewfinder Alignment Screws – adjust these screws to align the viewfinder.
    18. Viewfinder Alignment Bracket.
    19. Dust Cap
    20. Battery Compartment (not shown, underneath base).
