Meade ETX-80AT-TC Instruction Manual - Page 9

1% 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. 1^ Computer Control Panel: A.
