Meade LXD75 10in SCHMIDT-NEWTONIAN Telescope With Autostar

Meade LXD75 10in Schmidt-Newtonian Telescope

Diffraction-Limited Optics
Meade's 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.

Optical Tube Construction
Schmidt-Newtonian 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 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 mirrors are used in all Schmidt-Newtonian andoptical systems, providing exceptional thermal stability compared to similar manufacturers 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 you to achieve a precise focus.

Stable LXD75 German Equatorial Mount

• Sturdy Mount with Heavy-Duty Castings
  Designed by Meade's engineers and manufactured for high-performance observing and astrophotography.
• &
  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 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 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 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.
