CHOOSING AN EYEPIECE
, page 14, and
TOO MUCH POWER,
page 16, 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.
