The 12" LX90-ACF has an 12” diameter f/10 ACF optical system (focal length 3048mm) and Ultra-High Transmission Coatings (UHTC) for maximum image brightness and contrast. This largest of the LX90 models collects over twice as much light as an 8" telescope, effectively doubling the image brightness on faint deep sky targets. 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 an incorporated 16 channel genuine Sony GPS receiver. The Autostar 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, 26mm Series 4000 Plössl eyepiece, Meade AutoStar® Suite Astronomer Edition Software for PC and an 8x50 viewfinder with quick release bracket. Scope weight is 60 pounds with 19 pound tripod. Ships in 2 boxes.
Product carries full one year Meade factory limited warranty.
Aperture: 12-Inch. Focal Length: 3048mm. Focal Ratio: f/10. UHTC Coatings, 1.25-Inch Diagonal Prism. LX90-ACF For the truly discerning astronomer who will not tolerate anything but the very best, there is Meade's Advanced Coma-Free (ACF) optical system. ACF takes all of the features of our SC models and then ups the ante. 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 Meade AudioStar features audio files and an internal speaker. This computerized celestial object locating system plugs into the telescope's handbox port allowing a quick telescope alignment.
Once aligned with the sky the AudioStar is ready to take you to any object in the over 30,000 object database. In addition to GOTO and tracking capability the AudioStar permits a wide array of fascinating and educational functions such as multiple Guided Tours, digital positional readouts, the ability to link with a PC using optionally available software and cord, and much more.
AudioStar Controller #07640 is compatable with the StarNavigator, ETX, LT, LX80, LX90, and LXD75 series telescopes.
Meade LS 6" ACF LightSwitch telescope. This award-winning 6" f/10 (1524mm focal length) powerhouse telescope is feature packed and portable. Meade's Patented automatic self alignment system aligns with just one touch of the power switch. Just flip the switch and walk away. It aligns itself. It’s that simple.
Meade's best Advanced-Coma Free optics deliver performance only seen previously in systems costing thousands of dollars more. With its standard Ultra High Transmission Coatings (UHTC) the LS gives you the sharpest, brightest optical system for its size available at any price.
The included AutoStar III GOTO keypad computer has an over 100,000 object library and guided tour functions. Includes Meade ECLIPS color CCD camera (640x480 resolution) which lets you capture images of your favorite celestial wonders and display them in real time on an external (user supplied) monitor or store them on a (user supplied) SD card so you can do CCD imaging your very first night out.
The included “Astronomer Inside” feature delivers over four hours of fun and informational audio presentations which can be heard over the built in speaker, and 30 minutes of video presentations and animations plus hundreds of still images which can be watched over an external (user supplied) TV or monitor. Imagine being given a brief and entertaining video presentation on Saturn while viewing that planet and its fabulous rings for the very first time. This telescope truly does it all.
Eight (user supplied) C cell batteries will run the telescope for 3-5 hours, with a Meade Universal A/C power supply available separately for longer observing sessions. (See recommended accessories, below.) Includes a highly rigid single fork mount featuring aluminum construction with massive 4.875" precision worm-gears. Standard equipment also includes a sturdy, adjustable height tripod with steel legs for great stability and vibration damping and a Series 4000 Meade 26mm Super Plossl eyepiece (59X magnification). Additional eyepieces available separately, compatible with all Meade and other brand 1.25” barrel size eyepieces.
Meade LightSwitch technology- bringing the fun back to Astronomy. This changes everything.
