The LX90-ACF: Meade’s popular LX90 with its great combination of highly usable electronic features, solid and relatively light weight mount, and very reasonable cost, goes to the next level with the revolutionary ACF optical system.
The patented Meade Advanced Coma-Free (ACF) optical design offers the coma-free pinpoint star images and flatter image fields greatly desired by discerning amateur astronomers, astrophotographers and professional observatories alike. This system also reduces the astigmatism and eliminates the diffraction spikes found in classical Ritchey-Chrétien designs. No competing Schmidt-Cassegrain Telescope can make those claims.
The 10" LX90-ACF has a 10” diameter f/10 ACF optical system (focal length 2500mm) and Ultra-High Transmission Coatings (UHTC) for maximum image brightness and contrast. Electronics include the advanced Meade 497 AutoStar computer system with over 30,000 object library, multiple guided tours, High Precision Pointing capability, and Meade SmartDrive with Permanent Periodic Error Correction.
Precise and quick star alignment is done near effortlessly with Meade's patented Level North Technology alignment system incorporating a 16 channel genuine Sony GPS receiver. The Autostar is flash-updatable via free downloads at Meade.com (optional cable required).
All LX90-ACF models feature the solid and stable LX90 aluminum double fork mount, with fast slew speed adjustable from 1 to 7 degrees per second. 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 a generous 60 hours (optional Meade Universal AC adapter also available). The mount also has mechanical locks in both axis allowing adjustment even without power.
The LX90-ACF comes fully equipped with a heavy duty height adjustable Meade Field Tripod, 1.25" diagonal prism, Series 5000 26mm 5-Element Plössl eyepiece, and Meade AutoStar® Suite Astronomer Edition Software for PC. The telescope also includes two separate viewfinders: an easy to use zero magnification red dot viewfinder controlled via the keypad with adjustable brightness and blink functions, and additionally a conventional 8x50 optical viewfinder with quick release bracket.
Scope weight is 50 pounds with 19 pound tripod. Ships in 2 boxes.
