Meade LX-Series

The large apertures of Meade LX-Series catadioptric (mirror-lens) telescopes permit the use of higher observing magnifications than is the case with smaller instruments, and because of the telescopes' greatly increased resolution and resolving power, extremely fine celestial detail may be observed and photographed. The four principal satellites of Jupiter become finite-sized orbs rather than pinpoints; the planet itself, under favorable atmospheric conditions, is an intricate web of whirls, festoons, and discontinuities. Saturn's rings resolve into finer detail, with at least 3 rings observable, and with detectable color variations. Six of Saturn's satellites are visible in revolution about the planet. Numerous features of the Martian landscape, including the white polar cap, are clearly identifiable. The Moon is a veritable treasury of incredibly fine fault lines, craterlets, and rilles. Deep-space phenomena take on a new character when explored through the tremendous light gathering capability of the 7", 8", 10", 12", and 14" models. Galaxies merely visible in smaller telescopes begin to show their essential structure; globular star clusters are resolvable in fine detail, in some cases to the core of the cluster; diffuse gas clouds such as the Orion Nebula are visible in such wide extension that the nebulosity may fill the field of view. This listing only hints at the breadth of galactic and extragalactic objects visible through the eyepiece of a Meade 8", 10", 12", or 14" SCT or 7" MCT model: it is a rare observer who might in a lifetime view all of the enumerated phenomena in the above categories.

Meade Schmidt-Cassegrain Optics: In astronomical optics the term diffraction-limited is used to rank an optical system as being of professional quality. Simply put, diffraction-limited means that the performance and resolution of an optical system are limited only by the size of the theoretical stellar diffraction image - i.e., limited only by the inherent aperture of the system and by the laws of physics. Meade hand-matched and hand-figured Schmidt-Cassegrain and Maksutov-Cassegrain optical systems - in continuous, independent, random tests by advanced amateurs and in definitive test reports by leading astronomical magazines - are consistently ranked as diffraction-limited. That Meade Schmidt-Cassegrain and Maksutov-Cassegrain optics carry such a reputation worldwide is perhaps the prospective purchaser's best assurance of optical quality.

Astrophotography: Many Meade Schmidt-Cassegrain owners have done fine, high-resolution photography of the Moon, planets, and deep-space, as the photos on these pages confirm. A large complement of optional accessories is available for virtually every type of photographic application. CCD Imaging: Creating a multifold increase in the effective aperture of any Meade telescope, CCD imagers enable the imaging of the planets and deep-space objects with a level of resolution and detail therefore impossible to achieve. Many of the finest astronomical images in this catalog were obtained with a CCD imager.

8" LX90 Schmidt-Cassegrain: Announced in June, 2000, the Meade 8" LX90 Schmidt-Cassegrain is the first full-capability, computer-controlled 8" Schmidt-Cassegrain ever offered in its price range — a telescope that includes many advanced features:

Dual-Axis worm-gear drive system: With 4.9"-diameter gears for smooth sidereal-rate tracking and slewing, the LX90's microprocessor-controlled drive system allows for precise long-exposure photographic or CCD imaging.

Autostar Computer Controller: Use Autostar to GO TO any of over 30,000 celestial objects in the LX90 database or to any object of known RA and Dec., automatically, at the push of a button and at a speed of 6.5°/second on both axes, simultaneously. The telescope's pointing precision is a remarkable 5-arc minutes or better.
