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.
