Parts Listing Getting the telescope ready for first observations requires only a few minutes. When first open-ing the packing box, note carefully the following parts: • The ETX Astro Telescope with fork mount system. • #494 Autostar handbox with attached coil cord. • MA 25mm and MA 9mm eyepieces, ea...

The power, or magnification of a telescope is determined by the focal length of the telescopeand the focal length of the eyepiece being used. To calculate eyepiece power, divide the tele-scope's focal length by the eyepiece's focal length. E.g., a 25mm eyepiece is used with theETX-60AT. The focal le...

It is important to understand that menu selections are set in a loop ( Fig. 9). This means that pressing the Scroll Down key ( 7, Fig. 3) cycles down through all the available options within a given category, then returns to the first option. The Scroll Up key ( 6, Fig. 3) cycles up through the opti...

If you are experiencing any problems with pointing accuracy, follow the proceduredescribed in “APPENDIX D: TRAINING THE DRIVE,” page 35, to insure accurate point-ing and tracking. • Tracking Rate: Changes th...

Terrestrial Observing The ETX-60AT and ETX-70AT make excellent high-resolution, terrestrial (land) telescopes.Viewing terrestrial objects requires looking along the Earth's surface through heat waves.These heat waves often cause degradation of image quality. Low power eyepieces, like theMA 25mm eyep...

Observing a Satellite NOTE: Satellite observing is an exciting challenge. Most satellites are in low orbit,traveling at approximately 17,500 mph. They move quickly across the sky and arevisible only for a few minutes, requiring Autostar to slew the telescope rapidly. Bestviewing is near Sunrise or S...

A wide assortment of professional Meade accessories are available for the ETX-60AT andETX-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.

General Maintenance The ETX-60AT and ETX-70AT telescopes are precision optical instruments designed to yield alifetime of rewarding applications. Given the care and respect due any precision instrument,your telescope will rarely require factory servicing or maintenance. Maintenance guidelinesinclude...

Troubleshooting The following suggestions may be helpful with operation of the ETX-60AT or ETX-70AT. The power indicator light on the telescope does not come on or there is no responsewhen pressing Autostar Arrow keys:• Verify that the Computer Control Panel power switch ( 10C, Fig. 1) is in the ON ...

Telescope moves off a terrestrial object while observing:• Verify that the vertical and horizontal locks have been tightened to a "firm feel" ( 6 and 9 Fig. 1). Telescope pauses when changing slew direction:• This pause is normal. A terrestrial object appears reversed left-for-right:• An eye...
