Additional Unique Features Equipped with additional features such as automatic over-current protection, automatic clutch protection for both axes, easy 3-point level adjustment, dual scope setup with two dovetails and more-- The MiniTower is one of the most user-friendly GOTO mounts available today.
2. MiniTower Assembly There are two shipping boxes. One box contains the hard case and mount components. The other box contains the tripod and counterweight. You may find that your tripod differs from the one shown here. Later models have star shaped Level Adjustment Screws (#6) without Level Adjustment Lock (#5) (based on customer feedback).
2.1. MiniTower Assembly 1. Setup tripod. Extend tripod legs to full extension. Then lock legs using the lock knobs on sides. Next expand the legs out to their maximum position. Figure 6 2. Assemble the three prong washer and azimuth clutch lock (#11) onto the mount base Washer Figure 7...

(1:1X) to the fastest (9:MAX). The other HBX is reserved for accessories, such as electronic focuser, laser pointer and autoguider adapter. DO NOT plug non-iOptron accessories into the unit to avoid damaging the mount or accessories. Figure 11 7. This step allows you to attach the counterweight or a second scope.
(#17) Figure 15 2.2. OTA Mounting and Balancing The iOptron MiniTower™ can handle various OTAs. A dovetail plate is needed to mount an OTA onto the MiniTower mount. The width of the MiniTower dovetail holder is 1.75”.
M6 set screws Figure 16. Secondary Dovetail and set screws A combination of a light OTA and a CW can be used to balance a heavier primary OTA. 2.3. Operate a MiniTower on Batteries Open the battery compartment door to install batteries. Pull the battery holder out from the mount carefully, making sure not to pull the wires loose.

The MiniTower can be controlled by a number of popular astronomy software programs. For astronomy software that does not have an embedded iOptron mount driver, an ASCOM driver and related platform are needed. Please refer to Appendix F for more...
4. Getting Started ® In order to experience the full GOTO capability of GoToNova technology it is very important to set up the mount correctly before observation. 4.1. Level and Align the Mount 4.1.1. Level the Mount. Leveling is critical for a good GOTO and tracking accuracy. First, loosen tripod rod (#4) and tripod lock (#1) a little.
Once it is straight re-tighten the altitude lock to make sure OTA is secure and will not spin. 4.2. Setting Up the Mount A MiniTower is equipped with a GPS receiver, which will receive the local time, longitude and latitude information from satellites after the link is established. However, manual input is still needed for time zone and Daylight Saving setting.
The site coordinates information can be found from internet, such as GPSVisualizer (http://www.gpsvisualizer.com/geocode), by entering the city name or address. In case you only find the site information in decimal format you can convert them into d:m:s format by multiplying the decimal numbers by 60.
Use the ◄ or ► key to move the cursor to the bottom of the screen, use the ▲ or ▼ button to toggle between “Y” and “N”. Press ENTER to go back the previous screen. The local time also can be manually entered in case of GPS malfunction or testing the mount inside. The time and site information will be stored inside HC memory chip.
R.A. anti-backlash: 0150 steps One steps equal to 1.5 arc second. To adjust steps move the cursor to each digit and use the number keys to input number directly. Press ENTER – “DEC anti-backlash” will display: DEC anti-backlash: 0150 steps One steps equal to 1.5 arc second.
4.3. Turn Off the Mount When you are finished observing it is recommended to return the mount to Park Position. If the mount is not moved then no initial set up is needed when you turn on the mount next time. To park the telescope press the MENU button, scroll down to “Park Telescope” and press ENTER.
5. Use the MiniTower 5.1. Manual Operation of a Telescope You may observe land and astronomical objects using hand controller’s arrow keys. After the telescope was assembled (referring to Section 2. Telescope Assembly), flip the I/O switch on the telescope mount to turn on the mount. Use ►,◄,▼ or ▲ buttons to point the telescope to the desired object.
