Grand Eye - LXD75 series

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, 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 Aluminum 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 center 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.

The Meade LXD75 German Equatorial Mount is suitable for observation and precise astrophotography, this new series sets a new Meade standard in their price class for steadiness, easy operation, high accuracy and smooth movement. Meade have created this backlash-free EQ mount incorporating heavy-duty castings and four high-precision stainless steel ball bearings in both RA and Dec axes. The LXD75 drive system has enhanced precision alignment of the motor gear assembly for greatly reduced backlash and tracking smoothness with high reliability. The heavy-duty, all-metal field tripod utilizes a locking spreader bar (with three 1.25" eyepiece holders) to lock each leg in place, fully eliminating flexure. Each leg has two anodized aluminum leg extension locks with an internal brake to eliminate slipping of the internal extending leg. These locks are inward facing so that no accidental bumping of the leg locks can occur.
