Step 5. Plug in hand controller and AC adaptor.
Plug hand controller into either one of the two HBX ports on the
mount. Next plug in AC adaptor. (Or use batteries—see step 3).
Turn on power (the red light should go on).
At this point you can begin observing manually. Use the 4 Arrow
keys (▲▼◄►) to rotate the scope Up, Down, Left, and Right.
Use the SPEED key to change the slew rate from the slowest
(2X) to the fastest (MAX).
The other HBX is reserved for accessories, such as external GPS
module, electronic focuser or laser pointer. DO NOT plug non-
iOptron accessories into the unit to avoid damaging the
mount or accessories.
For 80mm Refractor (#8502)…….....................................................
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.
For 114mm Newtonian (#8503) …….................................................
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)
Insert the eyepiece: Slide the eyepiece into the open end of the
eyepiece holder. Tighten the thumbscrews to a firm feel only.
Remove the round dust cover lid from the end of telescope.
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 lower power
eyepiece (such as a 25mm eyepiece) to get a wider field of view.
Later on you can change to higher powers.
