    Heavy Telescope Payload

    The CRUX T4000 is amazingly efficient, weighing 50 kg (110 lb) and able to carry payloads almost 4 times its weight with optional counterweights. The harmonic drive that moves this mount offers excellent tracking performance due to its zero-backlash design. The CRUX T4000 does not require any counterweights for payloads up to 60 kg (132 lb) and a full 180 kg (396 lb) with the optional 12 kg (26.5 lb) counterweight and counterweight shaft. The whole setup is designed to be the end-all mount for even the most extreme astronomy applications.

    The Harmonic Drive EQ Mount 

    The CRUX T4000 utilizes the P-motion Control system to control cycle errors in the gears. This can minimize the tracking error to less than ±3 arcseconds. In other words, you'll likely be able to take a 20-minute exposure using a medium-sized refractor without using a guiding system!

    TITAN TCS Software

    This incredible telescope mount is equipped with the most advanced telescope control system, the TiTaN1 TCS, to realize the highest ease of use and control among mobile systems – with or without a computer. The TiTaN TCS controller has high power and the ability to scale and supports advanced wireless environments as well as a connection via serial or USB.
