More Info

The LX800 German Equatorial Mount with StarLock from Meade is a robust portable German equatorial mount for advanced amateur stargazers, researchers, and astrophotographers. This computerized mount, counterweight, tripod, and autoguide system is engineered to handle a 90 lb instrument payload and delivers precise alignment and guiding that are unrivaled at this price. Constructed from machined stainless steel and aerospace grade aluminum, the LX800 is a durable and extremely stable platform designed for years of accurate movement.

At the core of the LX800 Series Mount is Meade's StarLock technology. StarLock uses both a wide field and a narrow field digital camera to identify guide stars as faint as 11th magnitude, then communicates information to the right ascension and declination assemblies to track celestial objects for precise one arcsecond guiding. Unlike standard autoguiders, StarLock directly transmit specific real-time commands to each of the servo motors, resulting in enhanced accuracy and faster guide corrections to within one arcsecond.

AutoStar II GoTo software makes setting up and observing celestial bodies both user-friendly and relatively easy. Over 144,000 objects are pre-loaded on the AutoStar handbox, all stargazers need to do is enter the moon, artificial satellite, planet, star cluster, or galaxy of their interest on the AutoStar handbox and the mount will automatically slew the telescope into alignment so the object appears in the center of the eyepiece.

LX800 Series Mount

Construction
Machined stainless steel and aircraft grade 6061-T6 aluminum form a durable and extremely stable platform capable of accommodating a 90 pound instrument payload. Precision roller bearings on both RA and DEC axes, and 0.68" diameter brass worms and 5.8" diameter 225-tooth aluminum gears deliver smooth, precision movements of the optical tube assembly.
Internal Cabling
Internal channels to route mounting and accessory cables prevents snags during setup and observations.
Counterweight
A 1.75" diameter threaded stainless steel counterweight shaft with 18 pound threaded stainless steel counterweights provide easy and safe adjustments of telescope balance.
AutoStar II GoTo System
The 144,000 object database puts moons, planets, star clusters, and galaxies at your fingertips. Simply push of the GoTo button and AutoStar II will align itself with the celestial object of your interest.

StarLock Automatic Guiding

Full-Time Automatic Guide Star Selection
Regardless of target, StarLock automatically identifies a suitable guide star as faint as 11th magnitude and locks on. Once locked on, guide corrections are automatically made until you slew to another target or turn it off. Unlike standard autoguiders that issue guide corrections in the form of speed and time, the StarLock communicates directly with the motor controllers providing specific commands in real-time, resulting in more accurate and faster corrections.
Ultra-Precision Pointing
StarLock uses its two cameras to refine pointing to an accuracy of one arcminute, which ensures the selected object will end up on your imaging sensor, a must of those faint objects you cannot visually confirm.
Drift Alignment Assist
Automatically selects and slews to two guide stars then uses its guiding optic to capture an image as a reference. The Drift Alignment program then calculates the distance the mount must be adjusted to precisely align with the celestial pole before moving the optical tube the calculated distance to re-center the guide star using the altitude and azimuth controls on the mount head. This feature dramatically speeds up the drift alignment process.
Lightswitch Alignment
Automatically centers alignment stars using its two cameras, taking the guesswork out of alignment.
