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.
