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 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¢X/sec. to 1x sidereal¡Xit¡¦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.
