to find a guide star, you can adjust the direction the guide scope is
pointed within the bracket by alternately loosening and tightening
the three thumbscrews on the front or back ring (usually you won't
need to make adjustments on both rings). Just make sure that all
six thumbscrews are tightened before you begin guiding. Do not
over-tighten them, however, or you could strip the screw threads!
Using the 60mm Multi-Use Guide Scope as a
Finder Scope
The 60mm Multi-Use Guide Scope conveniently doubles as a
60mm finder scope with the addition of an optional 1.25"-barrel
eyepiece inserted into the focuser collar (Figure 5). You may need
to slide the extension tube out nearly all the way to reach focus with
the eyepiece.
The 60mm Multi-Use Guide Scope has a focal length of 240mm, so
use of a 25mm eyepiece will yield a finder scope magnification of
9.6x (240 divided by 25).
You will need to align the finder scope with the main telescope
before starting your observing or imaging session. You do that by
adjusting the three thumbscrews on one or both of the bracket
rings until a distant object in the main telescope's eyepiece is also
centered in the finder scope's eyepiece. Use of an optional cross-
hair eyepiece is helpful in achieving exact centering of an object.
caring for the 60mm Multi-Use Guide Scope
To keep dust from getting inside the guide scope and from accumu-
lating on the objective lens, keep the front and rear caps installed
when the guide scope is not in use. We recommend storing the
guide scope in a padded accessory case.
Cleaning the Lens
Although it shouldn't need cleaning very often, you can clean the
front lens of theguide scope with any quality optical lens cleaning
tissue and optical lens cleaning fluid designed for multi-coated
optics. Never use regular glass cleaner or cleaning fluid designed
for eyeglasses. Before cleaning with fluid and tissue, eject any
loose particles from the lens with a blower bulb, compressed air,
or a soft brush such as a LensPen. Then apply some cleaning fluid
to a lens tissue, never directly on the optics. Wipe the lens gently
in a circular motion, then remove any excess fluid with a fresh lens
tissue. Oily fingerprints and smudges can be removed using this
method. Use caution, as rubbing too hard may scratch the lens.
Never re-use the same tissue.
