Brand new V2 , what's the difference? *Compared with the old model, a 12V power input port is added to improve the stability of power supply (Note: 12V power supply is mandatory) This mini motorised camera rotator is both ASCOM and Indi compatible and provides a strong, lightweight high speed rotator at 4.5 deg / second. The large m54 opening provides a wide light path for popular camera. The ultra low 11.5mm profile is perfect for systems with limited back focus. The unique structure makes the rotator as rigid as an adapter ring at any angle High Payload Maximum payload of 5 Nm* *The torque generated by the imaging equipment to the rotator must be less than 5 Nm. For example, if the center of gravity of the equipment is 10cm away from the rotator, the maximum weight of the equipment should not exceed 5kg. High speed, High precision* 4.5 degrees/sec After two attempts, the accuracy is better than 0.1 degrees.* The resolution can reach 0.01 degree. *After setting backlash correctly Ultra lightweight Only 420 grams Ultra low-profile Only 10mm Zero flexure guaranteed Patented magnetic design Absolute zero flexure is guaranteed at any PA De-rotation For users of altazimuth and Dobson telescopes Dimension *The torque generated by the imaging equipment to the rotator must be less than 5 Nm. For example, if the center of gravity of the equipment is 10cm away from the rotator, the maximum weight of the equipment should not exceed 5kg. Specification What's included
