The 12" LX200-ACF has 12” diameter f/10 ACF optics (focal length 3048mm) and Ultra-High Transmission Coatings (UHTC™) for maximum image brightness and contrast. The primary mirror is oversized so as to collect more outer field light, thereby reducing vignetting. The aspheric secondary mirror eliminates coma, thus rendering round star images and improved resolution across the full field.
Features the advanced LX200 AutoStar II computer system with 145,000 object library, multiple guided tours, High Precision Pointing capability with sub arc-minute pointing accuracy, and Meade SmartDrive with Permanent Periodic Error Correction.
Precise and quick star alignment is done near effortlessly with Meade's level north technology alignment system incorporating a 16 channel GPS receiver. The Autostar II is flash-updatable via free downloads at Meade.com (optional cable required). The drive base of the telescope has multiple input and output ports including an RS-232 PC interface and jacks for a (user supplied) CCD Autoguider and illuminated reticle.
All LX200 models feature a primary mirror locking mechanism, which effectively prevents movement of the primary mirror during long exposure astrophotography or observing. Turn the lock knob located just above the telescope's main focus knob and the progressive-tension primary lock completely cancels any residual image shift due to mirror movement during visual, photographic, or imaging applications.
All LX200-ACF models feature the DC-servo driven super heavy duty double fork mount, the strongest and most rigid mount in its class. Fast slew speeds are from 1 to 8 degrees per second, and can be user selected at .1 degree per second increments, while fine slewing and photographic guiding speeds can be adjusted from .01x to 1x sidereal in one one-hundredth increments. The mount and all electronics are internally powered by 8 (user supplied) C-cell batteries which will typically operate the telescope for about 20 hours (optional Meade Universal AC adapter also available). The mount additionally has mechanical locks and slow motion manual controls in both axes if for some reason you found yourself without power.
The 12" LX200-ACF comes fully equipped with the heavy duty height adjustable Meade Giant Field Tripod, 1.25" diagonal prism, Series 4000 26mm Plössl eyepiece, 8x50 viewfinder with quick release bracket and Meade AutoStar® Suite Astronomer Edition Software for PC. Telescope and drive weight is 34kg (75 lbs), and the tripod weight is 22.7kg (50 lbs). Ships in 2 boxes.
