Building on the success of their Cube and MiniTower mounts, iOptron upgraded the payload capacity and speed to create their MiniTower Pro Alt-Azimuth Mount. This versatile and highly flexible motorized computer-controlled unit is ideal for most star gazing or astrophotography duties with the ability to function as a dual-mount for two OTAs. Both axis motors are built into a small single unit which is compatible with all telescope OTAs with a Vixen or larger Losmandy dovetail plate up to 33lb including accessories. The unique design eliminates dead spots enabling you to point your telescope to any point above the horizon, unlike other mounts which tend to block the telescope tube at certain points of rotation. A secondary Vixen-style plate is included and replaces the counterweight to enable a dual-OTA setup. This additional mounting option makes this mount ideal for observation/astrophotography rigs, star parties, or other specialized observational requirements. This secondary mounting point has a maximum payload capacity of 10 pounds making it ideal for smaller refractors or Cassegrain scopes. A hard carrying case for the mount and accessories is included for safe storage and transport, and a 2" stainless steel tripod is also provided so all you need is a compatible OTA to start your observation session.
Included with the mount is the Go2Nova 8401 computer controller. This handheld unit features a 130,000 object database with 256 user-defined customizable objects for your favorite celestial bodies. The easy-to-use menu-driven system displays on a 8-line 21-character back-lit screen. This fully GoTo-capable unit has automatic tracking for fast moving near-space objects such as the Moon and planets, and slower moving deep-sky objects like nebulae and galaxies. For set-up or manual use, it has nine slew speeds starting at 1x and topping out at 4°/sec. To help you get observing faster, the controller has multiple alignment procedures, plus a 32-channel GPS receiver that provides the mount with accurate day/time/location information in both the Northern and Southern hemispheres. For improved tracking, you have the ability to program out periodic errors that might occur during long-duration tracking, and there is also backlash compensation to eliminate settling that might occur at certain points due to the gaps in the gears. The Go2Nova controller is powered by the mount to make use easier and simple while reducing the unit's weight.
