Leisure Time LX20 - Manual (Page 5)

INTRODUCTION
As a new LX200 owner, you are preparing for a journey into the
universe with the most advanced amateur telescope ever
produced. The advent of this instrument is the culmination of
twenty years of innovation and design at Meade Instruments;
never before have the features you have in your hands been
available to amateur astronomers: from robotic object location to
the revolutionary Smart Drive and the most stable mounting
structure ever. Your telescope comes to you ready for adventure;
it will be your tour guide and traveling companion in a universe of
planets, galaxies, and stars.
Meade 8", 10", and 12" LX200 Schmidt-Cassegrain and 7"
Maksutov-Cassegrain telescopes are instruments of advanced
mirror-lens design for astronomical and terrestrial applications.
Optically and mechanically, the 7", 8", 10", and 12" telescope
models are perhaps the most sophisticated and precisely
manufactured telescopes ever made available to the serious
amateur. These telescopes enable the visual astronomer to reach
out for detailed observations of the Solar System (the planets:
Jupiter, Saturn, Mars) and beyond to distant nebulae, star
clusters, and galaxies. The astrophotographer will find a virtually
limitless range of possibilities since, with the precision Meade
worm-gear motor drive system, long exposure guided
photography becomes not a distant goal, but an achievable
reality. The capabilities of the instrument are essentially limited
not by the telescope, but by the acquired skills of the observer
and photographer.
The 7", 8", 10", and 12" LX200 are, with the exception of a few
assembly operations and features, almost identical
operationally. Most standard and optional accessories are
interchangeable between the three telescopes. The instructions
in this manual generally apply to all three telescopes; when
exceptions to this rule occur, they are clearly pointed out.
Important Note: If you are anxious to use your Meade LX200
Telescope for the first time, at the very least be sure to read
TELESCOPE ASSEMBLY (page 7), and QUICK START (page 9)
sections of this manual. Thereafter, we urge you to read the
balance of this manual thoroughly at your leisure, in order that
you may fully enjoy the many features offered by the
instrument.
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 telescopes' pushbutton electric slewing,
digital readouts, Smart Drive, and much more open up visual and
photographic capabilities heretofore undreamed of.
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 degrees per sec. (6 degrees 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
degrees 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.
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.
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.
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!
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.
