The ETX-90 Maksutov-Cassegrain offers terrific optical quality that is the envy of the telescope industry, the easy to use Meade AutoStar computer handbox with over 30,000 object library, and a solid mount and tripod. Special package includes bonus accessories and case. If you are in looking for a high quality portable scope absolutely loaded with features and performance you need look no further. The Meade ETX-90 telescope features an advanced Maksutov-Cassegrain design for pinpoint star images and extraordinary contrast, making it a great deep sky performer and ideal for detailed lunar and planetary observation as it easily soars to high magnifications. This 90mm (3.5") model has a focal length of 1250mm (f/13.8) with Meade's best Ultra-High Transmission Coatings (UHTC).
Electronics include the Meade AutoStar keypad with over 30,000 object library and which can be linked to a PC using an optionally available software and cable connector set, allowing the telescope to be controlled via a laptop or other PC. The telescope is conveniently powered by 6 (user-supplied) AA batteries, and an AC adapter is also available for separate purchase. Standard equipment includes two high performance Meade Series 4000 1.25" diameter eyepieces in focal lengths of 26mm and 9mm (magnifications of 48X and 128X), carry case, easy to use red dot viewfinder, and portable but extremely stable Meade Model 884 field tripod with chrome plated tubular steel legs and built-in wedge. Also includes Meade AutoStar Suite Astronomer Edition Software and Instructional DVD to locate objects in the night sky, print star maps, and learn more about the use of your new telescope.
A telescope is only as good as its mount and this mechanically sophisticated model includes an extremely rigid dual fork design. The similarly advanced optical tube design incorporates a unique flip mirror mechanism, allowing light to either go to the comfortable 90 degree observing position of the eyepiece or the built in camera attachment port at the rear of the tube. Camera adapters sold separately.
For the casual or beginning observer the Meade ETX-90AT may be all the telescope ever required. Or, for the advanced astronomer who already owns a larger instrument, the ETX-90AT is the perfect ultraportable, 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. 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.
#497 Autostar Computer Controller One of the most important advances in telescope control in the past 25 years, the Meade #497 Autostar Computer Controller turns the ETX-90AT, ETX-105AT, or ETX-125AT into an automatic celestial object locating system. Just plug the Autostar into the telescope's HBX port, do a quick (less than one minute!) telescope alignment, and you're ready to observe any object in the Autostar's 30,000-object database.Best of all, the Meade Autostar is easy to use. Even the most novice observer will find himself or herself locating dozens of fascinating celestial objects the very first night out - from commonly-observed objects such as the rings of Saturn, the satellites of Jupiter, and the Orion Nebula (M42); to more difficult objects such as the Ring Nebula (M57) in Lyra, the Spiral Galaxy (M33) in Triangulum, and the Sombrero Galaxy (M104) in Virgo; to very obscure objects near the telescope's threshold of visibility such as the diffuse nebula NGC 6559 in Sagittarius, the galactic star cluster NGC 1778 in Auriga, and the spiral galaxy NGC 3310 in Ursa Major. The #497 Autostar Computer Controller is included as standard equipment with ETX-90AT, ETX-105AT, and ETX-125AT Astro Telescopes. Any of Autostar's database objects can be called up and entered on the hand controller display in seconds. The observer then simply presses the GO TO pushbutton and watches as the telescope automatically slews (moves) to the object and places it in the field of view. The effect of Autostar is to bring objects easily within reach which were previously unreachable for all but the most dedicated of amateur astronomers. Includes: * Maksutov-Cassegrain optical tube assembly (D=90mm, F=1250mm, f/13.8) with EMC super multi-coatings; * Internal flip-mirror system for either straight-though or 90 degree observing position; * Fork mount with electric slow-motion controls, setting circles and locks on both axes; * Electronic control panel; * 9 (from 2x sidereal to 5 degree/sec) dual-axis motor drive system with #497 Autostar controller; * Sidereal-rate tracking in equatorial mode with optional table tripod or deluxe field tripod; * Internal battery compartment accepting eight (user-supplied) AA-size batteries; * 8 x 21mm erect-image viewfinder; * Series 4000 Super Plossl 26mm eyepiece (1.25"); * #497 Autostar Hand Controller * #884 Deluxe Field Tripod * Operating instructions. * 15" x 7.3" x 8.5" * Telescope Net Weight: 9.2 lbs. * Telescope Shipping Weight: 12.4 lbs.
