The instrument cube on the Cassegrain focus is currently the only point for mounting instruments on LDT. The instrument cube supports up to 5 instruments at one time; one on the through port, two on the larger side ports (A & C), and two on smaller side ports (B & D). The simultaneous mounting of instruments supports very fast (~2 minutes) changeover between instruments and allows for multiple instruments to be used in a single night (or simultaneously, as in the case of NIHTS & LMI).
