INSTALLING THE DIAGONAL
The diagonal is a prism or mirror that diverts light at a right angle to the
light path of the telescope. This allows you to observe in positions that are
physically more comfortable than if you looked straight through.
To attach the diagonal onto the optical tube:
1. Loosen the adapter ring
set screws located on
the end of the focuser.
2. Slide the 2” barrel end
of the diagonal into the
focuser adapter ring.
3. Tighten the set screw
on the adapter ring to
hold the diagonal in place.
If you wish to change the orientation of the diagonal, loosen the thumb
screw on the focuser draw tube. This will allow the diagonal (or camera for
photography) to rotate freely. Rotate the diagonal to the desired position and
tighten the screw.
INSTALLING THE EYEPIECE
The eyepiece is an optical element that magnifies the image focused by the
telescope. To ensure that your telescope properly reaches focus, the eyepiece
should be inserted into the diagonal.
To install an eyepiece:
1. Loosen the set screw
on the diagonal until the
compression ring inside
the diagonal is loose
enough to slide remove
the plastic dust cover.
2. Slide the chrome portion
of the eyepiece into the
diagonal.
3. Tighten the set screw on
the star diagonal to hold
the eyepiece in place.
To remove the eyepiece, loosen the set screw on the diagonal and slide the
eyepiece out.
