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. |
