  We introduce the Chromospheric Telescope (ChroTel) at the Observatorio del
Teide in Izana on Tenerife as a new multi-wavelength imaging telescope for
full-disk synoptic observations of the solar chromosphere. We describe the
design of the instrument and summarize its performance during the first one and
a half years of operation. We present a method to derive line-of-sight velocity
maps of the full solar disk from filtergrams taken in and near the He I
infrared line at 10830 \AA.
