Mirror Adjuster MT100-SM in the SUNRISE balloon carried solar observatory - Precision Assemblies Construction of a flying telescope This positioning system is used as a mirror adjuster for a telescope suspended from a helium balloon, which ascended to an altitude of 24,000 meters to observe the sun as part of the SUNRISE mission of the Max Planck Institute for Solar System Research (MPS). The linear stage with a drive that consists a ball screw and stepper motor is used for high-precision adjustment of the planes of the 3rd and 4th deflection mirrors in the "Sunrise" solar observatory. This is necessary because the structure of the telescope bends depending on its position due to its suspension on a wire. These positioning systems compensate for these deformations by moving the mirrors back to the optically correct position. These two actuators are supported by the M2 three-axis actuator for the secondary mirror.
