2.2. OTA Mounting and 
Balancing 
The iOptron MiniTower Pro™ can handle 
various OTAs. A dovetail plate is needed to 
mount an OTA onto the MiniTower Pro 
mount. The width of the MiniTower Pro
TM
dovetail holder is 1.75”.
Most telescopes come with a dovetail plate 
installed on the bottom of the telescope. If 
the size of dovetail plate does not match un-
screw the plate and install an appropriate 
dovetail plate that matches the holder. 1.75” 
dovetail plates are available from iOptron at 
www.iOptron.com (part number #8422) or 
visit an online or local camera store. 
Some telescopes may not have screw holes 
on the bottom. In this case you may need 
compatible mounting rings to attach the 
dovetail plate. The size of the mounting 
rings should match the aperture of your 
OTA. 
The counter weight (CW) is always helpful 
to balance the OTA in order to have smooth 
groove
