Meade ACF-SC telescopes:
Almost every large telescope worldwide is a Ritchey-Chrétien, including NASA's Hubble space telescope. The technology used by the pros can now belong to you too. Meade's new Advanced Coma-Free System - powerful and high-precision - is within the reach of all ambitious amateur astronomers, astrophotographers and CCD photographers! It provides perfectly sharp star images, at the highest professional observatory level, over the entire field of view. The secret of coma-free system is - as the name says - the complete absence of coma, an optical aberration in which starlight is distorted and pulled into comet-like tails outside the central part of the image. Whether for observing or photography, the ACF Cassegrain optics from Meade is way ahead of conventional mass produced telescopes. It offers fantastic image quality, previously only available from Ritchey Chrétien telescopes and other exotic systems costing several times as much as the Meade system.
The mounting LXD75:
Light and transportable, but already equipped with a Go To control, the LXD75 is ideal for the advanced entrancy in astronomy. First astro-photographic steps can be performed and developed. The mounting is already equipped with another engine in both axes, which update astronomic objects and positions them up to 4,5° per second. Accuracy-gear in both axes allows a handling with a minimum of work with all 9 tempi. The Auto Star Handbox with Go To- funktion controls the LXD75 exactly and safe. The mounting is photographically resilient up to 8 kg and already equipped with PEC (Periodic Error Control).
LXD-75 20.3cm(8") ACF
20.3 cm(8") 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 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.
