[ toc ] 1. What Is the LX200? An Overview
Meade LX200 SCT's mark a new era in telescope technology for the amateur astronomer, whether
beginner or seasoned veteran. For the beginner, LX200 electronics permit the location and observation of
the major planets as well as hundreds of deep-sky objects the very first night you use the telescope. For
the experienced amateur the telescope's pushbutton electric slewing, digital readouts, Smart Drive, and
much more open up visual and photographic capabilities heretofore undreamed of.
[ toc ] a. Heavy-Duty Mounts with 9-speed Dual-Axis Electronics
DC-servo-motor-controlled worm gear drives on both telescope axes permit observatory-level precision in
tracking, guiding, and slewing. The 9-speed dual-axis drives cover every possible contingency of telescope
positioning: Press the SLEW button on the keypad controller for rapid motion of the telescope across the
skies at up to 8 ° per sec. (6 ° per sec. for the 12" LX200) on both axes simultaneously; once near the
target, switch instantly to the FIND speed for centering in the viewfinder at 2 ° per sec. Observing the
object in the main telescope, use the CNTR speed (32x sidereal) to place the object in the center of the
field. During long-exposure astrophotography press the GUIDE button for precise corrections at 2x sidereal
speed.
[ toc ] b. Built-in 64,359-Object Library
Enter into the keypad any of the 110 Messier objects, 7,840 of the finest NGC objects (galaxies, diffuse or
planetary nebulae, star clusters), one of the 8 major planets from Mercury to Pluto, one of 351 alignment
stars or any one of 56,050 SAO, UGC, IC or GCVS objects, press GO TO, and the telescope automatically
slews, or moves, to the object at up to 8° per sec., centering it in the main telescope field.
[ toc ] c. Altazimuth Mode Operation
For all visual observing applications, and for lunar and planetary photography, Meade LX200's may be set
up in the Altazimuth mode. Just attach the telescope's drive base directly to the tripod, use the fast 1-star
alignment procedure, and the telescope's computer actuates 2-axis tracking that keeps objects precisely
centered in the field, even at high powers, during the entire observing session.
[ toc ] d. Terrestrial Operation
Meade LX200's make incredible land-view telescopes. Set the telescope up in the Altazimuth format,
activate the Land menu option on the telescope's computer, and use the Keypad to track land objects on
both axes at any of the same 4 drive speeds!
[ toc ] e. Keypad and Power Panel Functions
The multifunction capability of LX200's includes direct connection of popular CCD autoguider/imagers; RS-
232 serial interface with a personal computer (PC), allowing the user to perform all of the Keypad functions
through, or write custom telescope software for a PC; brightness level control of an illuminated reticle
eyepiece from the Keypad and including special pulse-mode reticle operation.
