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 aluminium 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, providing 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.

2" Focuser Aluminium rack and pinion focuser allows the user to achieve a precise focus.*

Eyepiece Holder Accepts both 1.25" & 2" eyepieces. Allows use of all common telescope accessories and cameras.**

8 x 50 Achromatic Viewfinder Easily locate and centre deep sky objects (N-6EC model includes 6 x 30 viewfinder).

Made in the U.S.A. and Performance Tested All Meade
Schmidt-Newtonian and Schmidt-Cassegrain optics are manufactured at Meade’s state-of-the-art facility in Irvine, California—then performance tested on an Interferometer.

STABLE MEADE^{^®} LXD75™ GERMAN
EQUATORIAL MOUNT
Sturdy Mount with Heavy-Duty Castings
Designed by Meade’s engineers and manufactured
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 centre 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 corrections 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 Auto Star 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 provides 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.

MEADE^{^®} AUTO STAR^{^®}
The Auto Star 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. Auto Star is pre-programmed with several guided tours, including the popular Tonight’s Best. Input date, time and location—then let Auto Star take you on a guided tour of the best objects that particular night. The Auto Star controller can be updated. Log on to Meade.com to download software upgrades, guided tours, and timely objects like comets—free. Keep your Auto Star up-to-date and your telescope will grow with you for years to come.
