and accurate GOTO and tracking. The heavier the OTA, the more necessary it is to use a CW. For lightweight OTAs, i.e.
If you have a secondary OTA on the secondary dovetail holder, make sure you align it with the primary OTA. This alignment is done easier during the daytime. Point the primary telescope to a target at a remote building or flagpole and center the target in the eyepiece. Loosen the secondary dovetail holder lock (#15). Rotate the secondary OTA around the counter balance shaft (#18). Center the object in the eyepiece of the secondary OTA. If the secondary OTA is tilted, it can be adjusted by two tilting adjustment screws as shown in Figure 15 (M6 x 12mm Allen set screws, not supplied).

A combination of a light OTA and a CW can be used to balance a heavier primary OTA.
2.3.Operate a MiniTower Pro on Batteries
To install batteries open the battery compartment door. Pull the battery holder out from the mount carefully making sure not to pull the wires loose. Insert 8 AA batteries (not included) according to the diagram on the holder. Replace the battery holder back to the battery compartment and replace the cover. (See Figure 16)

MiniTower Pro™
The mount will draw a significant amount of current when performing GOTO and slew operations. The battery operation time varies depending on the battery quality and operation conditions. It could last from couple of hours to tens of hours. Use only fresh batteries and do not mix fresh and old batteries. Insufficient battery power may cause error messages.
