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
