Automating the Vatican Advanced Technology Telescope for feeding VATT-light into PEPSI.

Potsdam Echelle Polarimetric and Spectroscopic Instrument for the LBT, high-resolution polarimetric spectrograph

PEPSI during daytime: disk-unresolved solar light is fed to the spectrograph from a small Sun-as-a-star telescope. The upgrade SDI-POL will feed polarised light via two fibers to the spectrograph.

A robotic wide-field telescope with a FOV of 50 square degrees to support the PLATO mission

A high-resolution survey of TESS target stars near the northern ecliptic pole.

PLATO (PLAnetary Transits and Oscillation of stars) is a satellite mission that will continuously observe a 100 000 stars in a field-of-view of ~2250 sq.deg. using a suite of 24 telescopes.

RoboTel is a smaller copy of STELLA. It serves as a robotic test telescope as well as for educational purposes.

Robotic telescopes for stellar activity. Instruments are an Echelle spectrograph and a wide-field imaging photometer.

The Large Binocular Telescope on Mt. Graham in Arizona is equipped with two 8.4-metre-diameter mirrors mounted in parallel like binoculars.

Originally intended as a replacement for the canceled Eddington ESA-mission, to be brought to Dome-C, Antarctica. Discontinued due to unclear access situation on Dome-C.

Acquisition, Guiding and Wavefront sensing unit for the Large Binocular Telescope, Mt. Graham, Arizona. It will collect the light with two 8.4m mirrors.
