Meade ETX-90PE instruction manual Object appears in the SmartFinder but not in the eyepiece

Object appears in the SmartFinder but not in the eyepiece:

•The SmartFinder is not properly aligned with the telescope (see ALIGNING SMARTFINDER, page 13).

Slew speed does not change when you press the SPEED key or the telescope moves slowly even though the fast slew speed is chosen:

• The battery power may be low (see HOW TO ASSEMBLE, page 12).

Telescope does not track a celestial object:

•Make sure that the telescope is correctly aligned. See AUTOMATIC ALIGNMENT, page 17, for more information.

Images through the eyepiece appear unfocused or distorted:

•The magnification may be too high for the viewing conditions. Back off to a lower power eyepiece (see CHOOSING AN EYEPIECE, page 14).

•If inside a warm house or building, move outside. Interior air conditions may distort terrestrial or celestial images, making it difficult, if not impossible, to obtain a sharp focus. For optimal viewing, use the telescope outside in the open air instead of observing through an open or closed window or screen.

•If viewing a land object on a warm day, heat waves will distort the image (see

TERRESTRIAL OBSERVING, page 15).

•For clear viewing of objects, turn the focus knob (8, Fig. 1b) slowly since the “in- focus” point of a telescope is precise. Turning the focus knob too quickly may cause the focus point to pass without notice.

•The optics within the telescope need time to adjust to the outside ambient temperature to provide the sharpest image. To cool down the optics, set the telescope outside for 10 to 15 minutes before observing begins.

Telescope moves off a terrestrial object while observing:

•Verify that the vertical and horizontal locks are tight (see TELESCOPE FEATURES, page 6).

Telescope does not move past a certain point:

•The built-in vertical or horizontal rotational “stops” may have been reached. See #6, page 7.

Telescope pauses when changing slew direction:

• This pause is normal.

A terrestrial object appears reversed left-for-right:

•An eyepiece in the standard 90° observing position (4, Fig. 1b) reverses an object left-for-right: To view a correctly oriented image requires the optional #932 Erecting Prism (see OPTIONAL ACCESSORIES, page 42).

Meade Customer Service

If you have a question concerning your ETX model, call the Meade Instruments Customer Service Department at (949) 451-1450. Customer Service hours are 7:00 AM to 6:00 PM, Pacific Time, Monday through Friday. In the unlikely event that the ETX requires factory servicing or repairs, write or call the Meade Customer Service Department first, before returning the telescope to the factory, giving full particulars as to the nature of the problem, as well as your name, address and daytime telephone number. The great majority of servicing issues can be resolved by telephone, avoiding return of the telescope to the factory.
