Product description:
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 LX90 mount:
Observing the starry heavens is now even easier, with this mount requiring no previous knowledge of the night sky. Simple set it up and go: all you have to do is to confirm a pre-positioned reference star suggested by the mount. The mount works on the same principle as large professional observatories and already contains the positioning data for over 30,000 celestial objects in the AutoStar hand box supplied: 13,235 DSOs, the complete Messier, Caldwell, IC, and NGC catalogues, 16,888 stars sorted by name and SAO number, 8 planets, the Moon, 26 asteroids, 15 comets and 50 artificial satellites. 200 targets can also be specially programmed by the user. All of these objects are slewed to quickly, precisely, quietly, and reliably: the GoTo function works at 9 different, freely selectable positioning speeds: 6.5°/S, 3°/S, 1.5°/S or 128x, 64x, 16x, 8x, 2x and 1x sidereal speed. The AutoStar hand box can be updated with the latest software via the Internet at any time. There are also databases for comets, asteroids, artificial satellites, etc. available for downloading on the Meade website. This means that the accuracy of the coordinates is ensured at all times and the LX90 is always up to date.
The motorized, 125mm diameter, worm-drive on each axis ensures precise tracking of all objects, even for long exposure astrophotography. The computer-optimized double fork mount features very high stability whatever the orientation of the OTAand is also extremely light weight. The proven, vertically adjustable Meade tripod ensures an almost vibration-free setup: an important aspect which contributes significantly to the overall performance of the system. The setup can be selected between altazimuth or equatorial. The AutoStar software suite supplied allows you to control the mount from an external computer; an autoguider port is available as an option. Operation can be via 12V batteries, car battery or plug-in power supply.
