About this product
A fully-automatic 8” Schmidt-Cassegrain telescope with Meade ACF optics.
The Meade Advanced Coma-Free (ACF) optical design offers coma-free pinpoint star images and flatter image fields greatly desired by amateur astronomers, astrophotographers and professional observatories alike. This system also reduces the astigmatism and eliminates the diffraction spikes found in classical Ritchey-Chrétien designs.
The 8" LX90 has an 8” diameter f/10 ACF optical system (focal length 2000mm) and Ultra-High Transmission Coatings (UHTC) for maximum image brightness and contrast. Electronics include the 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 with an incorporated 16 channel 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 eight (user supplied) C-cell batteries which will typically operate the telescope for 60 hours. The mount also has mechanical locks in both axis allowing adjustment even without power.
