Features an 8" aperture, 2032mm focal length, and f/10 focal ratio with Dual-Fork Mounting. Equipped with Ultra High Transmission Coatings (UHTC) and a resolving power of 0.456 arc-seconds for the improvement of brighter star clusters, more fine detail in nebulae, and greater surface features on planets. Includes a Series 4000 26mm Super Plössl eyepiece (96x), viewfinder (8x50 optical with crosshair), 1.25" Diagonal Mirror, and Standard Field Tripod. OTA and Mount Weight: 28 lbs. OTA Dimensions/Mount Dimensions: 25.5" x 14" x 19". Tripod Weight: 19 lbs. Tripod Dimension: 30" to 44" Variable.

The patented Meade Advanced Coma-Free (ACF) optical design offers coma-free pinpoint star images and flatter image fields greatly desired by discerning amateur astronomers, astrophotographers and professional observatories alike. This system also reduces astigmatism and eliminates diffraction spikes. This telescope also features Ultra-High Transmission Coatings (UHTC). UHTC are specialized multi-layered coatings that are precisely designed to improve the performance of your telescope's optics. You'll see brighter star clusters, more fine detail in nebulae, and additional surface features on planets. Averaged over the entire visible spectrum, total light transmission to the focus increases by 15%.

LX90 electronics include: advanced AudioStar computer system with a 30,000+ object-library, multiple guided tours, High Precision Pointing capability, and SmartDrive with Permanent Periodic Error Correction. Precise and quick star alignment is done near effortlessly with an incorporated 16-channel genuine Sony GPS receiver.

Feature a solid and stable aluminum double-fork mount with fast slew speed adjustable from 1.5 degrees to 6.5 degrees per second. Mount and electronics are internally powered by (8) x C-cell (user-supplied) batteries, which will typically operate the telescope for a generous 60 hours (optional Meade Universal AC Adapter can be used).

With high-quality features and performance, this model is a staple for your astronomy ventures. Make it your time to own "The Legend".
