AFOS: Probing the UV-visible potential of the Antarctic Plateau
The Antarctic Fiber-Optic Spectrometer (AFOS) is a 30cm Newtonian optical telescope that injects light through six 30m long optical fibers onto a 240−850nm spectrograph with a 1024 × 256 pixel CCD camera. The telescope is mounted on a dual telescope altitude-azimuth mount and has been designed to me...
