Aperture: 10-Inch. Focal Length: 2500mm. 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 item comes with a tripod.
