Meade ETX 90 AT UHTC GoTo Computer Telescope 3514-03-21 could be your Personal Window to the Universe. Meade ETX Telescopes are extremely versatile, high-resolution telescopes with features similar to those once available only with larger and more specialized imaging systems. With Meade Autostar Computer Controller, automatic tracking of celestial objects, and diffraction-limited imaging, Meade ETX-90 AT Telescope may be all the telescope ever required by many terrestrial and astronomical observers. Meade ETX-90AT UHTC Telescope with Autostar reveals nature in an ever-expanding level of detail. With Meade ETX-90AT Telescope you can observe the feather structure of an eagle from 50 yards or study the rings of Saturn from a distance of 800 million miles, focus beyond the Solar System and observe majestic nebulae, ancient star clusters, remote galaxies, and even stars recently discovered to have planets orbiting about them. Meade ETX Telescopes are instruments fully capable of growing with your interest and are ideal for both the casual observer and serious astronomer alike.

For the casual or beginning observer the Meade ETX-90AT UHTC Autostar Telescope may be all the telescope ever required. Or, for the advanced astronomer who already owns a larger instrument, the Meade ETX-90AT Telescope is the perfect diffraction-limited, ultra portable 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.

Optical Systems: Manufactured entirely at the Meade Irvine, California, facility, Meade ETX Maksutov Cassegrain Telescopes produce optical performance and resolution that equal or exceed any Maksutov optics of similar apertures ever manufactured at any price, past or present. Optics so high in contrast, image brightness, and resolution that Meade ETX Telescopes often out-perform many telescopes of larger apertures.

Meade #497 Autostar Computer Controller: Included with Meade ETX 90 AT Telescope the patented Meade Autostar Controller #497 brings automatic GO TO operation, plus dozens of additional menu options, to your fingertips, with a database of more than 30,000 celestial objects, including 5,386 galaxies, nebulae and star clusters from the Index Catalog (IC); 7,840 objects from the New General Catalog (NGC); 110 Messier objects; the major planets from Mercury to Pluto; and more.

Meade UHTC Ultra-High Transmission Coatings: Meade ETX 90 AT Telescope 3514-03-21 comes standard with amazing Meade UHTC optical coatings. Meade UHTC Coating permits the highest levels of light transmission (a 20% increase in total telescope light trans-mission compared to the standard-equipment coatings) ever offered on amateur telescopes.

Meade #884 Deluxe Field Tripod: Constructed of strong, lightweight steel, the full length Meade ETX Telescope Tripod #884 provides a rigid mounting platform for virtually any ETX observing application, including astrophotography.

Fork Mounts with Standard-Equipment Dual-Axis Drive System and Meade #497 Autostar Controller: The rigid fork mountings of Meade ETX-90 Maksutov-Cassegrain Telescope 35140321 include high-torque DC motors on both telescope axes, permitting electronic operation from the standard-equipment Meade Autostar Controller. With the telescope placed in the altazimuth mode on a table, astronomical object-tracking may be accomplished automatically, after a quick and easy 2-minute alignment of Meade Autostar to the sky. Alternately , Meade ETX-90 AT GoTo Telescope may be mounted in either the altazimuth or equatorial modes on the standard-equipment Meade #884 Deluxe Field Tripod.

Cordless Field Operation: The drive base of Meade ETX 90 AT Computer Telescope accepts eight (user-supplied) AA-batteries that power the telescope for about 20 hours of normal usage, negating any requirement for an external power source in the field. Alternately, Meade ETX-90 AT Telescope may be powered from an automobile cigarette lighter plug, using the optional Meade #607 Power Cord 07043.

Flip-Mirror System: Flip the internal, optical-flat mirror "up" for observing in the standard 90° position; flip the mirror "down" for terrestrial observing with the optional Meade #932 45 degree Erecting Prism 07210 or for photography with the optional Meade #64 T-Adapter 07363.
