OPTIONAL ACCESSORIES

A wide assortment of professional Meade accessories are available for the ETX-60AT and ETX-70AT. 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 inter- national 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) 451-1450or visit the Meade website at www.meade.com.

#506 AstroFinder™ Software and Cable Connector Kit: Displays more than 10,000 celes- tial wonders – galaxies, nebulae, star clusters, stars, and planets – on your PC, enabling even the beginner to locate and identify objects to observe with the telescope or to print out star charts for use in observing sessions. Operates with any Windows™ -based personal computer. The Cable Connector Kit permits connection of the ETX-60AT and the ETX-70AT, Autostar, and PC, for downloading of new software to Autostar or for updating of Earth satellite or other celes- tial object positions. This kit is included with each AstroFinder Software package.

Eyepieces: Meade Modified Achromatic eyepieces, supplied as standard-equipment with the ETX-60AT and the ETX-70AT, permit observing powers of 39X (MA 9mm) and 14X (MA 25mm). Optional eyepieces of the Plössl (PL) optical design yield higher and lower powers, combined with bright, sharp images. Any of these eyepieces may be used in conjunction with the #124 2x Barlow Lens or #128 3x Barlow Lens (below) to double or triple, respectively, eyepiece powers.

Meade Modified Achromatic (MA) and Wide Angle (WA) eyepieces in the standard American- size (1.25”) barrel diameter (Fig. 19) permit a wide range of magnifying powers with the ETX- 60AT and ETX-70AT. Powers obtained with each available eyepiece are shown in the follow- ing table:

		with #124	with #128
Eyepiece	Power	2x Barlow lens	3x Barlow lens
MA 9mm*	39X	78X	117X
MA 25mm*	14X	28X	42X
PL 4mm	88X	176X	264X
PL 5mm	70X	140X	210X
PL 6mm	58X	116X	174X
WA 18mm	19X	38X	57X

* Included as standard-equipment with the ETX-60AT and ETX-70AT

Meade Modified Achromatic (MA), Wide Angle (WA), and Plössl (PL) eyepieces are ideal for general-purpose astronomical or terrestrial observing. The typical ETX-60AT or ETX-70AT user may wish to add two or three of these eyepieces to his or her telescope. An introductory selec- tion might include the PL 6mm eyepiece, while the more advanced observer might select the PL 4mm, PL 5mm, and WA 18mm. The Meade Wide Angle 18mm eyepiece yields wide fields of view, perfect for the examination of star fields, diffuse nebulae, or for terrestrial applications.

#124 2x Barlow Lens and #128 3x Barlow Lens: For high-power astronomical applications these coated, amplifying lenses double (#124) or triple (#128) eyepiece magnifying powers without any reduction of image resolution. Example: By itself the PL 5mm eyepiece yields a power of 70X with the ETX-70AT; used with the #128 3x Barlow Lens, this eyepiece yields a power of 210X. Insert either Barlow Lens into the telescope's eyepiece holder, followed by an eyepiece.

These lenses are achromatic, high-performance, short-focus Barlow lenses, perfectly suited to the low-profile design of the ETX-60AT and ETX-70AT. Lens surfaces are coated for maximum image contrast and light transmission.
