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) 451-1450or visit the Meade website at www.meade.com.

#497 Autostar™ Computer Controller: One of the most important advances in telescope control in the past 25 years, the Meade #497 Autostar Computer Controller (Fig. 21) turns your ETX model into an automatic celestial object locating system. Just plug Autostar into the telescope’s HBX port in place of the standard-equipment Electronic Controller, do a quick telescope alignment, and you are ready to observe any object in the Autostar’s 14,000-object database.

Best of all, the Meade Autostar is easy to use. Even the most novice observer will locate dozens of fascinating celestial objects the very first night out — from commonly observed objects, such as the rings of Saturn, the satellites of Jupiter, and the Orion Nebula (M42), to more difficult objects, such as the Ring Nebula (M57) in Lyra, the Spiral Galaxy (M33) in Triangulum, and the Sombrero Galaxy (M104) in Virgo; to very obscure objects near the telescope’s threshold of visibility, such as spiral galaxy NGC 3310 in Ursa Major.

Any of Autostar’s database objects can be called up and entered on the hand controller display in seconds. The observer then simply presses the GO TO pushbutton and watches as the telescope automatically slews to the object and places it in the field of view. Autostar brings into easy access objects that were previously unreachable for all but the most dedicated of amateur astronomers.

AstroFinder Software/#505 Cable Connector Kit: With Meade AstroFinder software (Fig. 22) loaded into your PC, Autostar-equippedETX–90EC,ETX-105EC, and ETX-125EC telescopes 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. 23), 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 18mm. Under good seeing conditions, Meade Ultra Wide Angle 4.7mm and 6.7mm eyepieces present the widest obtainable fields of view at high powers and are well suited for observing the Moon and planets. Alternative optional eyepieces may be chosen from the Meade Series 3000 Plössl eyepieces. Powers obtained with each eyepiece are shown in the following table.

* Included as standard-equipment with the ETX models.

** Use these eyepieces only under extremely steady atmospheric conditions.

#126 2x Barlow Lens: An amplifying lens, the multi-coated #126 2x Barlow (Fig. 24) 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 SP 26mm eyepiece yields a power of 73X with the ETX-125EC; when used with the #126 2x Barlow Lens, this eyepiece yields 146X.
