Hobym Crux 200HDA Computerized German Equatorial Mount

The CRUX 200HD weighs just a bit over 28 lbs and is the most efficient equatorial mount in its class. It offers excellent performance for precise long focal length astrophotography due to its zero-backlash design, which is a major advantage of harmonic drives. The mount is equipped with additional ball bearings and thrust bearings on the RA and DEC axes to further enhance vibration and stiffness to protect the key components, harmonics, as well as the highest efficiency in terms of weight. Even without PEC, sub-arcsecond guided tracking is possible due to the instantaneous response to guide commands. The CRUX 200HD does not require any counterweights for payloads up to 40 lbs (18 kg). This ensures lower costs and much greater freedom in transporting the mount to remote locations.  For higher payloads, only a small amount of counter weighting is needed, unlike other equatorial mounts that need counterweights equal or heavier than the payload.


Because of this, the CRUX 200HD can fulfill the role of both a mid-size high-precision portable mount or a high capability permanent observatory mount. It is an excellent choice for remote use due to its outstanding performance, rigidity, and design that can meet the needs of discriminating astroimagers. The harmonic drives have an estimated lifespan that exceeds 100 years with near continuous permanent usage.  No other mount motor design can boast this level of dependability. 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 connection via serial or USB. 


The Crux 200HD uses P-motion Control, one of the core features of the TiTan TCS, to control periodic errors (PE) in an innovative way. As a result, running the in-mount PEC routine while autoguiding will result in a periodic error value below +/- 3 arcseconds.  Autoguiding will further reduce this to a fraction of an arcsecond.
