A fork mount at the left holds the sunlight-collecting end of the
telescope end parallel with the earth’s axis. A single mirror (1)
collects sunlight and reflects it into a 10-inch (25 cm) objective
lens in the short cylindrical tube(2). The beam of sunlight is
passed to two “dichroic mirrors” (3) and (4) which pass some
wavelengths of light and reflect the wavelengths chosen for our
research.
