* Refer to "CHOOSING AN EYEPIECE," page 14, and "TOO MUCH POWER," page 15, to
determine which optional eyepieces are best-suited to your applications and how to avoid
"overpowering" the telescope.
#140 2x Barlow Lens: An amplifying lens, the #140 2x Barlow doubles the power of all eye-
pieces with which it is used. Insert the #140 into the telescope's eyepiece-holder first, followed
by the diagonal prism and eyepiece.
#909 Accessory Port Module (APM): The #909 APM attaches to the rear cell of the LX90 and
connects by cable to the Aux port on the telescope's control panel. The APM includes auxiliary
connectors for plug-in of such accessories as corded models of illuminated reticle eyepieces,
the #1206 Electric Focuser, or a CCD autoguider.
#505 AstroFinder™ Software and Cable Connector Kit: With Meade AstroFinder loaded into
your PC, Autostar-equipped telescopes, such as the LX90, may be remotely controlled from the
PC display. The #505 Connector Cable Set, permitting connection of the LX90, Autostar, and
PC, is included with each AstroFinder package.
#928 45° Erect-Image Diagonal Prism: Primarily used for terrestrial viewing, this prism pres-
ents a correctly-oriented image at a comfortable 45° viewing angle.
Illuminated Reticle Eyepieces: Meade Illuminated Reticle Eyepieces are used for precise
polar alignment of your telescope. During long-exposure astrophotography, in conjunction with
the optional Meade Off-Axis Guider, they are used for through-the-telescope monitoring of the
object being photographed while the camera's shutter is open. Two optical designs are avail-
able: Series 4000 Plössl 9mm or Modified Achromatic 12mm. Each model is available in a wire-
less or corded configuration. The wireless models include a variable brightness control with
self-contained (user-provided) batteries. The corded models include variable brightness and
blink rate functions and plug directly into the Accessory Port Module (see above), with actua-
tion from the hand controller.
