Focus Knob: Moves the telescope’s objective lens (10, Fig. 1) in a finely-controlled motion to focus an image. The ETX-80AT telescope 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.

Note: The first time you focus the telescope, you may have to rotate the focus knob 20 to 40 complete turns as this is a fine focus mechanism which allows you to focus an image very precisely.

A. Handbox (HBX) Port: Plug the AutoStar coil cord (8, Fig. 5) 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.
