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 (#8602)……..... ................................................
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 (#8603) …….................................................
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 (#8604)… ……………………………….
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.
