About iOptron

The iOptron MiniTower Pro has all the same, great technologies and features- just beefed up! So, you can still mount two scopes on- but now with more pay load. You can still track objects-only now the encoder resolution is six times finer. It comes in with a two-inch stainless-steel tripod that is much taller for easier viewing with large scopes.

The MiniTower Pro can easily be carried around in a car trunk or as an airline luggage. The whole system takes only 10 minutes to assemble. This unlimited portability, combined with the internal GPS, gives amateur astronomers extreme flexibility in selecting an observing location.

Equipped with the most advanced SmartStar GOTO technology, MiniTower Pro is one of the most powerful and accurate GOTO mounts. The standard 8401 hand controller offers the superb navigation experience with an 8 line LCD back-lit display, a 130,000 object database and a USB port for easy connection with ASCOM compliant PC planetarium programs.

With a typical GOTO accuracy of 1 arc minute and the SmartStar precision auto-tracking, the MiniTower Pro will consistently bring the celestial object of your choice to the center of the eye-piece and keep tracking for hours.

Powered with other 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 much more, the MiniTower Pro is one of the most user-friendly GOTO mounts.

Needs Better Assembly/Setup instructions


from Fullerton, CA.  -  Avid Adventurer

Why oh why is there no documention included? Online instructions for assembly leave off fact that if one removes the altitude lock (per installing counterweight) and scope is inserted in mount parallel to ground (5" ES refractor)if its not balanced watch it roll over. Very guickly. P.S. attach the Azimuth lock (not mentioned in quick setup.) No balancing instructions. Makes a nice unit a 1st time assembly P.I.T.A.
