* 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 
eyepieces 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 (Fig. 19) 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 (Fig.
20) presents a correctly-oriented image at a comfortable 45° viewing angle.

Illuminated Reticle Eyepieces: Meade Illuminated Reticle Eyepieces (Fig. 21) 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 available: Series 4000 Plössl 9mm or Modified Achromatic 12mm. Each model is
available in a wireless 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 actuation from the hand controller.
