PREMIUM MEADE
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

STABLE MEADE LXD75 GERMAN
EQUATORIAL MOUNT
Sturdy Mount with Heavy-Duty Castings
Designed by Meade's engineers and manufac-
tured for high-performance observing and
astrophotography.
Shaft & Bearing System
All Meade
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
both axes for smooth tracking and slewing.
High-Precision Pointing (HPP)
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
the course of one or more training periods, thereby minimizing guiding cor-
rections during long-exposure photography.
9-Speed Drive Controls
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
Power Supply
Powered by 8 D-size batteries. Can also be powered
by optional car cigarette lighter or AC wall adapter.
