Outline
|
Meade¹s Schmidt-Cassegrain (SC) optics give you high performance for the best
possible price. For the person looking to get the most from their astronomical
dollar, look no further. Meade uses water-white glass with superior light
transmission across the entire visible spectrum, unlike inferior standard plate
glass used by other telescope manufacturers. Combined with Meade's industry-leading
Ultra-High Transmission Coatings (UHTC) -- with 15% better light transmission
than standard coatings -- and oversized, thermally-stable Pyrex® primary mirrors
for optimum light collection, you get a spectacular viewing experience not
available on comparable telesscopes.

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 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 Aluminium 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. You can download software upgrades,
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.
