Paper Abstract

The Chromospheric Telescope (ChroTel) is a 10 cm robotic telescope to observe the full solar disk with a 2k × 2k CCD at high temporal cadence. It is located at the Observatorio del Teide, Tenerife, Spain, next to the 70 cm German Vacuum Tower Telescope (VTT). ChroTel contains a turret system that relays a stabilized image of the solar disk into a laboratory within the VTT building. The control design allows a fully robotic operation. Observations are carried out in three chromospheric wavelengths (CaK: 393 nm, Ha: 652 nm, HeI 1083 nm).
