GPS Receiver. 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 locate 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.
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® Hand Controller. The industry standard. Used by more astronomers than any other system for everything from backyard observing and imaging to observatory research.
What is Advanced Coma Free?The Meade ACF-optical system has a great advantage when compared to conventional optics: it doesn´t have coma. Coma is a optical aberration that affects stars outside the middle of the image. The starlight is spread to form a cometlike tail. Meade Advanced Coma Free optics don´t have this aberration. You can see the difference with each look through the telescope: small round stars up to the edge of the field of view. The higher concentration of starlight also raises the contrast of the image and fainter stars get visible. If it is visual observing, or astrophotography: the Advanced Coma Free optics from Meade Instruments deliver the superior images when compared with conventional serial telescopes. Meade ACF telescopes provide a image qualitythat was in the past only available by Ritchey-Chretien telescopes and other exotic systems. Those telescope have prices that are much higher than the Meade ACF optics.
