Meade ETX-60AT instruction manual ETX Your Personal Window to the Universe

Except for the lens diameter, the Meade ETX-60AT and the ETX-70AT are identical; all procedures and descriptions in this manual apply to both telescopes.

CAUTION:

Using products other than standard Meade accessories may cause damage to the telescope’s internal electronics and may void the Meade warranty.

ETX: Your Personal Window to the Universe

The Meade ETX-60AT and the ETX-70AT are extremely versatile, high-resolution telescopes with features similar to those once available only with larger and more specialized imaging sys- tems. With pushbutton controls, automatic tracking of celestial objects, and software down- loading capability, an ETX telescope may be all the telescope ever required by many terrestri- al and astronomical observers.

Your ETX telescope reveals nature in an ever-expanding level of detail. Observe the feather structure of an eagle from 50 yards or study the rings of the planet Saturn from a distance of 800 million miles. Focus beyond the Solar System and observe majestic nebulae, ancient star clusters, remote galaxies, and even stars recently discovered to have planets orbiting about them. Meade ETX telescopes are instruments fully capable of growing with your interest and are ideal for both the casual observer and serious astronomer alike.

1Eyepiece - Place the MA 25mm eyepiece into the 90° Eyepiece Holder (3, Fig. 1) and tighten in place with thumbscrew (2, Fig.1).

2Eyepiece Holder Thumbscrew - Tightens the eyepiece in place. Tighten to a "firm feel" only.

390° Eyepiece Holder - Holds the eyepiece upright for easy viewing.

4Optical Tube - The main optical component that gathers the light from distant objects and brings this light to a focus for examination with the eyepiece.

5Movable Objective Lens Cell - This component contains the telescope’s lenses. The focus knob (8, Fig. 1) moves the cell for precise image focus.

6Vertical Lock - Controls the manual vertical movement of the telescope. Turning the ver- tical lock counterclockwise unlocks the telescope enabling it to be freely rotated by hand about the vertical axis. Turning the vertical lock clockwise (to a "firm feel" only) prevents the telescope from being moved manually, but engages the vertical motor drive for Autostar operation.

NOTE: The vertical lock knob (6, Fig. 1) is a knurled knob located on the fork arm to the right of the focus knob (8, Fig. 1). Mounted beneath the knob is a circular scale with no numbers. Do not confuse this scale with the Dec setting circle (17, Fig. 1) on the opposite fork arm which has a numbered scale used to locate astronomical objects.

CAUTION: When loosening the vertical lock, be sure to support the objective lens cell (5, Fig. 1). The weight of the objective lens could cause the tube to swing downward suddenly and damage the telescope.

7Fork Arms - Hold the optical tube in place.

8Focus Knob - Moves the telescope’s objective lens (5, Fig. 1) in a finely-controlled motion to achieve precise image focus. The ETX-60AT and ETX-70AT telescopes can be focused on objects from a distance of about 17 ft. to infinity. Rotate the focus knob clockwise to focus on distant objects, and counterclockwise to focus on nearby objects.

9Horizontal Lock - Controls the manual horizontal rotation of the telescope. Turning the horizontal lock counterclockwise unlocks the telescope, enabling it to be freely rotated by hand about the horizontal axis. Turning the horizontal lock clockwise prevents the tele- scope from being rotated manually, but engages the horizontal motor drive for Autostar operation.
