Stare mode exposures cover a FOV of 35 x 35 arcmin.
Some observations are currently done in scan mode, which gives an equivalent exposure time of 141 seconds. Typically, 10 minute scans are taken of pre-selected fields; each field is observed three times during a night. The fields are selected for objects with uncertain ephemerides. Scanning is only possible at declinactions below 20 degrees.
Under very good observing conditions objects between 19.5 and 20.0 magnitudes are readily detected. Typically, however, our limiting magnitude lies between 18.5 and 19.
