DEIMOS has a 7 position filter wheel that holds broadband imaging and long-pass order-blocking filters. Selecting the filter and focus value is typically done from the The Dashboard GUI. Double-clicking inside the FILTER FOCUS box on the dashboard opens the FILTER-FOCUS PANEL dialog shown above. Once the R-band focus value is set from the main Dashboard GUI, the focus offset for other filters (FOCUSOFF) is updated automatically.
