Meade ETX-90 AT f/13.8 Maksutov-Cassegrain
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 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.
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 Autostar Computer Controller can locate all of these objects automatically, in seconds.
The ETX-AT's include an internal flip-mirror system for either straight-through or 90º observing, an aluminum fork mount with electric slow-motion controls, setting circles and locks on both axes, electronic control panel, a 4-speed (8x, 32x, 0.75°/sec, 5°/sec) dual-axis motor drive system with sidereal-rate tracking in equatorial mode, and an internal battery compartment accepting eight (user-supplied) AA-size batteries.
