MEADE LXD75 8

LXD-75 8" ACF

8" (203 mm) f/10 Advanced Coma Free optics with German equatorial mount LXD 75 and AutoStar Computer control

Diffraction-Limited Advanced Coma Free optics yield pinpoint stellar images over an extremely wide field-of-view even for photografic use. Advanced Coma Free 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. Sturdy Mount with Heavy-Duty Castings Designed by Meades 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 telescopes 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 siderealits 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.
