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. |
