Next, move the tube upward or downward until the second displacement number
also reaches zero. As you near zero, use the vertical slow motion control (F, Fig.

Which One’s the Alignment Star?
If the control panel has chosen an alignment star with which you are unfamiliar,
how can you be sure if the star in your eyepiece is really the alignment star?
The rule of thumb is that an alignment star is usually the brightest star in that
area of the sky. If you're not sure if you have located the alignment star or it isn't
in the eyepiece, look through your viewfinder. When you view an alignment star
in the viewfinder, it stands out dramatically from the rest of the stars in that por-
tion of the sky. The viewfinder will help you locate a star more quickly than the
eyepiece, because it has a much wider field of view than the eyepiece.
If you have an obstruction, such as a tree or a building blocking your view of the
alignment star, or if you have any doubts at all about the star that has been cho-
sen, no problem. Just press UP/DOWN and the control panel will find another
star to align upon.
TIPS for Beginners
IMPORTANT NOTE:
As you observe
Saturn, you will notice
that the image moves
in the eyepiece. This is
because the Earth is
rotating. You can use
the horizontal and ver-
tical slow motion con-
trols (20, Fig. 2 and F,
Fig. 3) to re-center the
image in the eyepiece.
The image will move
much faster if you are
using a higher-pow-
ered eyepiece such as
a 4 mm or the 12mm
eyepiece.
