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-Chretien 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 AudioStar 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 an incorporated 16 channel genuine Sony GPS receiver. The AudioStar is flash-updatable via free downloads at Meade.com (optional cable required).
All LX90 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 comes fully equipped with a 1.25" diagonal mirror, Series 4000 26mm 5-Element Plössl eyepiece, and Meade AutoStar Suite Astronomer Edition Software for PC and an 8x50 viewfinder with quick release bracket.
