Using a LISA spectrograph on a large diameter telescope.
Nearby or in thousands of km, take control of your calibration & flat lamps for Alpy, Lhires III and LISA.
SPOX module : to remotely control the flat and calibration lamps for Alpy 600, Lhires III and LISA.
Realize a spectrum of a very weak object with a LIsa or an Alpy, it is possible.
