AIMING THE ASTROSCAN
®
1. Your ASTROSCAN
®
Millennium is adjustable
along two axes - altitude (up/down) and
azimuth (left/right). You can adjust the
telescope’s position along one or both axes at
the same time. (Figure 2)
2. Gently take hold of the end of the optical
tube and move it either left or right
(Figure 3) or up and down.
3. The telescope can be positioned to view
anywhere in the night sky, but be sure to let
it move naturally; never force your telescope
to move.
4. To tighten the altitude motion, simply tighten
the large altitude tension knob located on
the mount (E). You can adjust the tension so
that the telescope holds its position but still
easily moves by hand.
FOCUSING THE IMAGE
1. Insert the 17mm eyepiece into the
focuser.
2. Find a bright star and center it in
the eyepiece. When the image is out
of focus, the star looks like a doughnut.
If focusing during the day, find an
easily recognizable object like a sign or
streetlight.
3. Turn the focus knobs (M) until the star
focuses to a point of light. Bright stars
will sometimes show a plus-shaped
flare (called diffraction spikes)
coming from the secondary mirror
support at the front of the telescope.
4. Changing eyepieces typically requires
readjusting the focus.
