-
Meade LXD75 SN8-AT is an 8 inch Schmidt-Newtonian reflector type telescope, also known as an SNT, with 812mm focal length and fast f/4 aperture.
-
This Meade Newtonian reflector scope includes the Autostar 497 hand controller.
-
Meade Schmidt-Newtonian 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.
-
These Schmidt-Newtonian 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, preventing distortion of an otherwise sharp image, and helps keep the optics clean.
-
Water white glass is used in all Meade LXD75 Schmidt-Newtonian corrector lenses to maximize light transmission, for an increase of light transmission in excess of 10%, as compared to competitive telescopes using soda lime glass.
-
These Schmidt-Newtonian corrector lenses and mirrors are individually figured to create a superior optical system which is renowned for its exquisite smoothness and performance, with Pyrex® Premium-grade primary mirrors for exceptional thermal stability versus competing models using standard plate glass.
-
Meade Schmidt-Newtonians have extremely fast, well corrected F/Ratios for short photographic exposure times and wide fields-of-view.
-
The Autostar controller included with Meade LXD75 SN8-AT helps quickly find and goto over 30,000 objects, and can be updated via the Meade website.
-
8 x 50 Achromatic Viewfinder easily locates and centers deep sky objects.
-
Made in the USA and performance tested at the state-of-the-art Meade facility.
-
Sturdy Mount with heavy-duty castings designed by Meade engineers and manufactured for high-performance observing and astrophotography.
-
Sturdy German Equatorial Mount is accurate and precise, with RA and Dec axes that move effortlessly on four high-precision stainless steel ball bearings.
-
High-Precision Worm Gears on both axes for smooth tracking and slewing.
-
High-Precision Pointing (HPP) for even more precise pointing, putting objects in the center of the field-of-view allowing you to confirm deep sky objects at the faintest limits of the telescope capability.
-
Periodic Error Correction corrects periodic errors on the RA axis over the course of one or more training periods minimizing guiding corrections during long-exposure photography.
-
9-Speed Drive Controls From a rapid slew rate of 4.5°/sec. to 1x sidereal, controlled from the AutoStar controller.
-
3-Star Alignment ensures precise alignment while eliminating the need for a complicated optical/mechanical alignment process.
-
Heavy-duty 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.
