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.stronomer 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" LX90’s primary mirror is actually 8.25").This additional 1/4" yields a wider, fully illuminated field-of-view, and allows you to see the light other telescopes leave behind. 8 X 50 VIEWFINDER Quickly and easily located and center deep sky objects.
SLEW SPEED The LX90 slews (moves) from star to star at 7 degrees per second. That is more than twice as fast as the competition. This means that over the course of an evening, a Meade LX90 will show you two to three times more objects. RIGID CAST ALUMINUM FORK MOUNT The Meade LX90's Optical Tube Assembly is mounted on two sturdy fork arms giving you a rock solid platform for astrophotography. LX200™ - SERIES TRIPOD The LX90 comes standard with the same sturdy field tripod as the LX200-ACF series telescope. SMART DRIVE™ Meade’s AutoStar® provides Periodic Error Correction (in polar mode). Over the course of one or more training periods your LX90 will minimize guiding corrections during long exposure astrophotography. AUTOSTAR CONTROLLER Meade’s AutoStar® can be updated after purchase. Guided tours and timely objects like comets, satellites and new discoveries – Free! Keep your AutoStar up-to-date, and your LX90 will grow with you for years to come. | | | Specifications | 8" |
