Eyepieces are commonly referred to by focal length and barrel
diameter. The focal length of each eyepiece is printed on the
eyepiecebarrel.Thelongerthefocallength(i.e.,thelarger

the higher the magnification. Generally, you will use low-to-
moderate power when viewing. For more information on how
to determine power, see the section on
“Calculating Magnification.”
Barrel diameter is the diameter of the barrel that slides into
the star diagonal or focuser. The LCM uses eyepieces with a
standard 1-1/4” barrel diameter.
Focusing
To focus your telescope, simply turn either of the focus knobs at
the eyepiece end of the optical tube. Turn the focus knob until
the image is sharp. Once sharp, turn the knob towards you to
focus on an object that is closer than the one you are currently
observing. Turn the knob away from you to focus on a more
distant object than the one you are currently observing.
The StarPointer Finderscope
The StarPointer is the quickest and easiest way to point your
telescope exactly at a desired object in the sky. It’s like having
a laser pointer that you can shine directly onto the night sky.
The StarPointer is a zero magnification pointing tool that uses a
coated glass window to superimpose the image of a small red
dot onto the night sky. While keeping both eyes open when
looking through the StarPointer, simply move your telescope
until the red dot, seen through the StarPointer, merges with the
object as seen with your unaided eye. The red dot is produced
byalight-emittingdiode(LED);itisnotalaserbeamandwill
not damage the glass window or your eye. The StarPointer is
poweredbyalonglife3-voltlithiumbattery(#CR1620).Likeall
finderscopes, the StarPointer must be properly aligned with the
main telescope before it can be used. The alignment procedure
is best done at night since the LED dot will be difficult to see
during the day.
Install the Battery
1. Unscrew the battery cover on the StarPointer finderscope.
2. Insert battery with “+”side facing out.
3. Replace battery cover.
Aligning the StarPointer
1. To turn on the StarPointer, turn the switch to the “on”
position – see Figure 2-9
2. Locate a bright star or planet and center it in a low power
eyepiece in the main telescope.
3. With both eyes open, look through the glass window at the
alignment star. If the StarPointer is perfectly aligned, you
will see the red LED dot overlap the alignment star. If the
StarPointer is not aligned, take notice of where the red dot is
relative to the bright star.
4. Without moving the main telescope, turn the StarPointer’s
two adjustment screws until the red dot is directly over the
alignment star. Experiment as to which way each screw
moves the red dot.
The StarPointer is now ready for use. Always turn the power
off after you have found an object. This will extend the life
of both the battery and the LED.
Attaching the Hand Control
The LCM hand control has a phone jack type connector at the
end of its cord. Plug the phone jack connector into the outlet
on the top of the motorized base. Push the connector into the
outlet until it clicks into place and place the hand control into
its holder as described previously in the Assembly section of
the manual.
Powering the Telescope
The LCM can be powered by 8 user supplied AA size alkaline
batteries or an optional 12V AC adapter. To install batteries into
the LCM:
1. Press the tab on the front of the battery compartment and
remove the cover.
