The Meade 16" LX600-ACF is an f/8 Advanced Coma-Free Optical System, it comes with StarLock. Meade LX600 is a simple to operate, portable package that makes taking great astrophotos as easy as focusing your camera and opening the shutter. The collection of features and technology integrated into the LX600 is unavailable from any other manufacturer and cannot be duplicated by just attaching a set of add-ons to another scope.
The LX600 integrates a unique star tracking and object finding system into the telescope mount. This integration allows the telescope to center your target perfectly in the field of view. Once centered, the star tracking system communicates directly with the motor drives to automatically assure your scope stays locked onto its target with arcsecond precision. The automated optical tracking system delivers long-exposure guiding with pinpoint stars on astroimages despite misalignments, atmospheric refraction, periodic or other mechanical errors. This level of precision is unobtainable with systems using high precision encoders, software pointing models, large gears or PEC training - and all without the need of an external computer.
Meade f/8 Advanced Coma-Free Optical System has completely redesigned the OTAs with a new mirror mounting and focusing system to achieve zero image-shift and a two-speed microfocuser. The scope features faster f/8 ACF optics giving you pinpoint stars all the way across the field of view. Internal Crayford-style 7:1 Focuser completely redesigned mirror mounting system achieves zero-image shift, eliminating the need for a mirror lock and integrates a two-speed microfocuser for quick and easy adjustments.
In Alt/Az mode, the LX600 also makes for the best visual and short exposure experience possible. The LX600 performs LightSwitch fully-automated self alignment. StarLock will put every target dead center in the eyepiece and track with arcsecond accuracy so you can concentrate on the beautiful, wide fields of pinpoint stars created by the superb f/8 ACF optical system. Autostar II Controller puts over 145,000 objects at your fingertips with the fastest GoTo performance available (8 degrees per second), or you can control the system from an external computer.
