performance tested on an Interferometer.
MEADE AUTOSTAR
®
The AutoStar controller helps you quickly find, and GoTo over 30,000
objects in the night sky. View planets, stars, galaxies, nebulae, and
comets…all at the push of a button. AutoStar is pre-programmed with
several guided tours, including the
popular 
Tonight’s Best. Input date,
time and location— then let
AutoStar take you on a guided tour
of the best objects that particular
night. The AutoStar controller can be
updated. Log on to Meade.com to
download software upgrades, guided
tours, and timely objects like
comets—free. Keep your AutoStar up-
to-date and your telescope will grow
with you for years to come.

LXD75 OPTICS
Diffraction-Limited Optics Meade’s Schmidt-Newtonian and
Schmidt-Cassegrain optics yield pinpoint stellar images over an
extremely wide field-of-view with only half the coma of standard
Newtonians of the same focal ratio.
Optical Tube Construction Schmidt-Newtonian and Schmidt-
Cassegrain optics are mounted in precision-machined aluminum
cells, which are then mounted in sturdy steel tubes which are baked
with high-grade textured enamel paint. The optical tube assembly is
closed, reducing air currents inside the tube. This prevents distortion of
an otherwise sharp image. Plus, a closed tube significantly helps keep
the optics clean.
Corrector Lens Fully corrects for spherical aberration and 
provides pinpoint star images. Water white glass is used in all
Schmidt-Newtonian and Schmidt-Cassegrain corrector lenses to
maximize light transmission. The use of water white glass results in
an increase of light transmission in excess of 10%, as compared to
competitive telescopes using soda lime glass.
Individually Figured Optics Schmidt-Newtonian and Schmidt-
Cassegrain corrector lenses and mirrors are individually 
figured to create a superior optical system which is renowned for its
exquisite smoothness and performance.
Pyrex
®
Primary Mirror Premium-grade Pyrex mirrors are used in
all Schmidt-Newtonian and Schmidt-Cassegrain optical systems, pro-
viding exceptional thermal stability versus competing models using
standard plate glass.
Fast F/Ratios Meade’s Schmidt-Newtonians have extremely fast,
well corrected F/Ratios for short photographic exposure times and
wide fields-of-view.
*Excludes Schmidt-Cassegrain.  **SC-8 AT requires optional accessory
Sturdy Mount with Heavy-Duty Castings
Designed by Meade’s engineers and manufac-
tured for high-performance observing and
astrophotography.
Shaft & Bearing System The sturdy German
Equatorial Mount is accurate and precise. The
RA and Dec axes move effortlessly on four
high-precision stainless steel ball bearings.
High-Precision Worm Gears Located on
both axes for smooth tracking and slewing.
High-Precision Pointing (HPP) For even more
precise pointing use the HPP function. HPP puts
objects in the center of the field-of-view which allows you to
confirm deep sky objects at the faintest limits of the telescope’s
capability. 
Periodic Error Correction Corrects periodic errors on the RA axis over
the course of one or more training periods, thereby minimizing guiding cor-
rections during long-exposure photography.
9-Speed Drive Controls From a rapid slew rate of 4.5˚/sec. to 1x sidereal—
it’s all controlled from the AutoStar controller.
3-Star Alignment Ensures precise alignment while eliminating the need for a
complicated optical/mechanical alignment process.
Heavy-Duty Tripod Variable-height field tripod with spreader bar brace pro-
vides the stability and vibration damping required for visual observation and
astrophotography
.
Illuminated Polar Alignment Viewfinder For quick, precise polar alignment.
Power Supply Powered by 8 D-size batteries. Can also be powered
by optional car cigarette lighter or AC wall adapter.
