Focusing the Telescope
The VersaGo GX 80 is outfitted with a 1.25" rack and pinion fo-
cuser. To focus the image you will use the black focus wheels
(see Figure 8). Assuming you have installed a diagonal and
eyepiece to acquire a target image, turn the focus wheels to rack
the focuser drawtube in and out, changing the focal distance of
the light path. To ensure the sharpest focus go slightly past your
perceived focus point and then reverse directions until you have
a sharp focus.
You will have to readjust the focus when aiming at subjects of
varying distances, or after changing eyepieces. Make sure the
drawtube lock thumbscrew is loosened before focusing. After
focusing, you can tighten it to lock the telescope's focus into
place if desired.
