LX200 Telescope

I have a Meade 8" LX200 f/10 telescope which I purchased in 1995. 

The telescope has a light collecting aperture of 8" (203mm) and a focal length of 80" (2000mm), yet by virtue of its Schmidt-Cassegrain Catadioptric design, the telescope tube is only 16" long. Light enters the front of the telescope through a thin "correcting plate" lens of 8" diameter to a spherical primary mirror at the back of the tube, which reflects light to a convex secondary mirror sitting in the centre of the correcting plate at the front, this then reflects the light back through a central hole in the primary mirror to reach focus at the focal plane. The secondary mirror multiplies the effective focal length of the primary mirror and produces a very compact telescope for its aperture. The telescope's theoretical resolution is 0.56 arc sec. Maximum practical visual magnification power is x500, but I normally operate it using eyepieces which give a x77 - x209 magnification.


The telescope tube is mounted between heavy duty fork mounts and DC-servo-motor-controlled worm gear drives on both telescope axes permit high precision in tracking,  guiding and slewing. The telescope has a push button hand control with a red backlit digital readout display which is linked to the telescope's 16MHz 68000 microprocessor main control. The hand controller has a built in library of over 64,000 objects and after alignment, the telescope can be brought to bear on any of the objects with a simple GOTO function.  A series of more advanced functions are also available to achieve high-precision pointing and tracking.

The telescope can be used in altazimuth mode, land mode or polar mode. In the latter mode the telescope is fitted on top of a special Equatorial Wedge that tilts the telescope such that it's axis points directly to Celestial North (a point close to Polaris - The Pole Star - about which the stars appear to rotate, of course it is really the earth that is rotating).

LX200 Comments

My own experience and comments with regard to the 8" LX200 are in the process of being added here (please check back again soon).  All of the comments are my own. I hope that they will compliment and extend the advice and hints posted by other LX200 users.
