# On the TCS '''Advanced tab''', left-hand side under '''Telescope''', enter 80 in the Altitude box and enter an Azimuth to face the telescope in the opposite direction to the rising (270) or setting (90) Sun. Click '''Slew'''. Then immediately below the Slew button, click '''Tracking OFF'''.
# On the instrument PC, '''select the required filter'''. If you need flats in a variety of filters, be sure to cycle through them in the correct order (e.g. UBVRI during evening twilight; IRVBU in the morning). This also applies if you need a range of prebin settings (i.e. start with low binning in the evening; high to low binning in the morning).
# Take You can easily take a '''minimum of 15 flats in each filter/prebin setting'''with SHOC; Sibonise has longer readout times.
