Parts of the Telescope

1 = main mirror 2 = collimator mirror (moveable) E = Tübingen UV Echelle Spectrometer (TUES): 3 = cross disperser 4 = Echelle grating 5 = Echelle detector B = Berkeley Extreme and Far-UV Spectrometer (BEFS): 6 = Rowland grating 7 = detector 8 = star tracker 9 = cargo bay envelope of Space Shuttle 10 = telescope cover F = focus of main mirror and entrance diaphragm of the two spectrometers

Moving the collimator mirror into the light beam will reflect the light into the Echelle spectrometer.
If the collimator mirror is not in the light beam, the light will fall directly into the Berkeley spectrometer.
