Meade LX90-ACF 10-Inch (f/10) 30K object Database Advanced Coma-Free Telescope with Audiostar Hand Controller
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 497 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 heavy duty height adjustable Meade Field Tripod, 1.25" diagonal prism, Series 4000 26mm 5-Element Plössl eyepiece, and Meade AutoStar® Suite Astronomer Edition Software for PC and an 8x50 viewfinder with quick release bracket. Scope weight is 50 pounds with 19 pound tripod. Ships in 2 boxes.
Product carries full one year Meade limited factory warranty.

With it's technologically superior optical design, ACF gives a flatter, coma-free field of view with pinpoint images all the way to the edge of the field, rivaling Ritchey-Crétien performance at a fraction of the cost. ACF is the perfect solution for the serious astroimager or visual astronomer looking for observatory-class optics. GPS - LX90 can do more than track satellites. It talks to them as well. Turn it on and the built-in Sony GPS sensor immediately determines your precise date, time and location. AutoAlign then uses this info to align your scope for a tour of the most spectacular sights in the universe. EASY ALIGN –LX90s are smart scopes that know the night sky right out of the box. Easy Align picks two alignment stars for you and places them right in your viewfinder. Just center them to fine tune your alignment and the wonders of the universe are at your fingertips. OVERSIZED PRIMARY MIRROR – Only Meade manufactures their primary mirrors in diameters larger than their listed aperture (e.g. the diameter of the 8-Inch LX90’s primary mirror is actually 8.25-Inch).This additional 1/4-Inch yields a wider, fully illuminated field-of-view, and allows you to see the light other telescopes leave behind. The item comes with a tripod.
