OPTIONAL ACCESSORIES
A wide assortment of professional Meade accessories are available for the for ETX
telescopes. Meade accessories greatly extend many important applications to the
telescope, from low-power, wide-field terrestrial viewing to high-power lunar and
planetary observing. The premium quality of these accessories is well-suited to the
quality of the instrument itself.
Meade telescopes and accessories, including optional accessories for ETX
telescopes, are available at more than 3,000 dealer locations in the U.S. and Canada
and through Meade international distributors worldwide. Once you have identified the
accessories you wish to order, contact your local Meade authorized dealer. To find a
dealer near you call (949) 451-1450 or visit the Meade website at www.meade.com.
#505 Cable Connector Kit: With Meade AstroFinder
software loaded into your PC, AutoStar-equipped ETX–90PE and ETX-125PE tele-
scopes may be remotely controlled from the PC display. The #505 Cable Connector
Set, permitting connection of ETX, AutoStar and PC, is included with each
AstroFinder package.
Eyepieces: For higher and lower magnifications, Meade Super Plössl (SP) and
Super Wide Angle (SWA) eyepieces (Fig. 35), as well as the Series 4000 8mm to
24mm Zoom eyepiece, yield high-resolution imaging with all ETX telescope models.
A useful selection includes the SP 9.7mm, SP 12.4mm and SWA 16mm. Under good
seeing conditions, Meade Series 5000 Ultra Wide Angle 4.7mm and 6.7mm eye-
pieces present the widest obtainable fields of view at high powers and are well suited
for observing the Moon and planets (other eyepieces are available in this series).
Powers obtained with each eyepiece are shown in the following table.
#126 2x Barlow Lens: An amplifying lens, the multi-coated #126 2x Barlow (Fig. 36)
doubles the power of all eyepieces with which it is used. Insert the #126 into the
telescope’s eyepiece holder first, followed by an eyepiece. Example: By itself, the
26mm eyepiece yields a power of 73X with the ETX-125PE; when used with the #126
2x Barlow Lens, this eyepiece yields 146X.
#64 T-Adapter: The basic means of photography through any ETX Astro telescope,
the #64 T-Adapter threads to the rear cell of the telescope, followed by a T-Mount
appropriate to the user’s brand of 35mm camera. In this way, the camera body is
rigidly coupled to the telescope's optical system, which in effect becomes the cam-
era's lens (see PHOTOGRAPHY, page 38).
