    iOptron iEQ45-PRO Mount Head with Accessories

    The iOptron iEQ45-PRO Mount Head with Accessories - iOptron intended for the iEQ45 Pro Equatorial Mount Head Package from the very beginning of the conception to the very end of the construction to be complete with accessories for the range of entry-level to intermediate astrophotographers. This package is outfitted with a wide array of precision motors, zero-backlash gears, and to top it all of a computer controller to provide an absolutely ideal platform for imaging. The mount has a duel dovetail saddle that allows both Losmandy and Vixen-style plates for mounting compatible OTAs, and with a maximum payload capacity of 45 lb, it can easily hold large telescopes, counterweights, and accessories. The mount is motorized, with a Go2Nova 8407+ computer hand controller, and an illuminated polar axis scope for speedy alignment and set up! The mount also has a built in 32-channel GPS receiver that sends your location and time to the Go2Nova hand controller, allowing for quick and easy setup.

    The included dark-field illuminated AccuAligning polar axis scope installs through the body of the mount for accurate initial manual alignment, as well as alignment verification and correction during observation and imaging sessions. The iEQ25 is built for precise tracking, as required during long-exposure astrophotography, with highly accurate stepper motors and the ability for you to program out the Period Error Correction common to all worm gears.

    The dual-axis 1.8 degree stepper motor is controlled by the Go2Nova hand controller, both mentioned above. This system has an internal database of 359,000+ celestial objects, with sixty user-defined objects to program yourself for your own convenience. The controller has update-able firmware in the built-in serial port as well- and with nine slew speeds and automatic tracking capabilities, finding and keeping objects centered in the field of view is easy no matter if you're viewing the fast moving Moon, or much slower space subjects.
