This page shows specific directions for the 80mm Refractor, 114mm
Newtonian, and the 90mm Maksutov (depending on which telescope tube
your unit may come with).
. 80mm Refractor (#8502 and #8802) …….....................................................
Insert 45º diagonal:
Insert the diagonal into the eyepiece
side of the telescope. Tighten the thumbscrews to a firm feel
only.
Insert the eyepiece:
Slide the eyepiece into the open end of
the diagonal. Tighten the thumbscrews to a firm feel only.
Remove the dust cover from the other end of optical tube
assembly.
Use the focus knob
to bring objects into focus. You may
need to turn the focus knob quite a few turns to focus your
telescope for the first time. Always start observing using a
low power eyepiece (such as a 25mm eyepiece) to get a nice
wide field of view. Later you can change to high power if so
desired. Higher powered eyepieces have a much narrower
field of view. So it’s more difficult to initially locate objects
using higher powered eyepieces.
. 114mm Newtonian (#8503 and #8803) …….................................................
Attach the red dot finder scope to the telescope tube (#1):
First remove the two washers on the tube. Then place the
finder scope onto the two bolts and re-attach the washers
securely. The finder scope should face towards the open end
of the tube (see arrow in diagram).
Turn on the beam using the switch on the side. (note: you
may need to remove the plastic insulation placed next to the
battery underneath)
. 90mm Maksutov-Cassegrain (#8504 and #8804) ………………………………….
Install Diagonal by screwing it onto the back end of the
scope. You can adjust the position of the diagonal by
loosening the free-spinning threader on the diagonal.
Install the Finderscope by sliding the dovetail plate onto the
sleeve (see arrow) and tightening the side screw.
The eyepiece can be placed on the end of the scope or on
the side (see next step). Secure the eyepiece using the side
screw.
Use the focus knob to adjust the focus.
This picture shows the eyepiece on the side. Remove the
protective cap to insert the eyepiece. The diagonal is not
used for side viewing.
Use the flip switch to flip the internal mirror to view from the
side or the end of the scope.
