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.

 

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. 

 
 

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)

 

 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. 

 

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.
