(For 60 and 80mm Models)
The star diagonal diverts the light at a right angle from the light path of the telescope. For astronomical observing, this allows you
to observe in positions that are more comfortable than if you were to look straight through. To attach the star diagonal:
1.
Turn the thumbscrew on the eyepiece adapter at the end of the focuser barrel
until it no longer extends into (i.e., obstructs) the inner diameter of the focus
barrel. Remove the protective dust cap from the focuser barrel.
2.
Slide the chrome portion of the star diagonal into the focuser barrel.
3.
Tighten the thumbscrew on the focuser barrel to hold the star diagonal in
place.
If you wish to change the orientation of the star diagonal, loosen the thumbscrew on
the eyepiece adapter until the star diagonal rotates freely. Rotate the diagonal to the
desired position and tighten the thumbscrew.

The eyepiece is the optical element that magnifies the image focused by the
telescope. The eyepiece fits either directly into the focuser (114LCM models) or
into the star diagonal (60/80LCM models). To install the eyepiece:
For 60 and 80 models:
1.
Loosen the thumbscrew on the star diagonal so it does not obstruct the inner diameter of the eyepiece end of the diagonal.
Remove the protective dust cap from the star diagonal's barrel.
2.
Slide the chrome portion of the low power 25mm eyepiece into the star diagonal.
3. Tighten the thumbscrew to hold the eyepiece in place.
For 114 models:
1.
Loosen the thumb
screw on the eyepiece adapter at the end of the focuser
barrel and remove the protective dust cap from the focuser barrel.
2.
Slide the chrome portion of the low power 25mm eyepiece into the
eyepiece adapter.
3.
Tighten the thumbscrew to hold the eyepiece in place.
To remove the eyepiece, loosen the thumbscrew on the eyepiece barrel and
slide the eyepiece out.
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 number) the lower the eyepiece power or
magnification; and the shorter the focal length (i.e., the smaller the number)
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.
