10Computer Control Panel

A.Handbox (HBX) Port - Plug the Autostar coil cord (9, Fig. 3) into this port.

B.LED - The red power indicator light illuminates when power is supplied to the Autostar handbox and to the telescope’s motor drive.

C.ON/OFF Switch - Turns the Computer Control Panel and Autostar ON or OFF.

D.Auxiliary (AUX) Port - Provides connection for current and future Meade acces- sories, such as the Meade “AstroFinder Software with Cable Connector Kit,” which allows you to control your ETX from a PC. See “OPTIONAL ACCESSORIES,” page 25.

11Base Housing - Supports the telescope for placement on a flat, level surface, such as a tabletop or optional tripod. See “OPTIONAL ACCESSORIES,” page 25.

12Holes for Optional Tripod (not shown, on the bottom plate) - See your tripod’s instruc- tion sheet for mounting information.

13Right Ascension (R.A.) Setting Circle - See "APPENDIX A," page 31, for detailed infor- mation.

14 15 Cellback containing Flip-Mirror and Flip-Mirror Control Knob - ETX telescopes include an internal mirror. With the flip-mirror control in the “up” position, as shown in Fig. 2a, light is diverted to the eyepiece. With the flip-mirror control in the “down” position, as shown in Fig. 2b, light proceeds straight out the photo port for photography. See “PHOTOGRAPHY WITH THE ETX,” page 23.

NOTE: The flip-mirror control is in the “up” position when the control is vertical (perpendicular to the telescope tube). To place the flip-mirror in the “down” posi- tion, turn the control counterclockwise until it stops.

16Photo Port - Attach any 35mm camera with a removable lens to this port using an optional #64ST T-Adapter or attach the #933 Erecting Prism for correctly oriented images through the eyepiece. See “OPTIONAL ACCESSORIES,” page 25.

17Declination (Dec) Setting Circle (on left fork arm) - See "APPENDIX A," page 31, for detailed information.

18Autostar with attached coil cord - See page 7 for a description of Autostar’s features.

19Dust Cap - Unthread the dust cap counterclockwise from the front lens of the telescope.

NOTE: The dust cap should be replaced after each observing session and the power turned off to the telescope. Verify that any dew that might have collected during the observing session has evaporated prior to replacing the dust cap.

20Battery Compartment - Install batteries in this compartment. See page 10 for more information.
