The larger dichroic mirror(3) reflects the sunlight to the smaller one(4) which reflects the
beam to the entrance aperture that allows a 10 X10 arc minutes field-of-view of the Sun(5).
The first focus showing the whole Sun is at the entrance aperture. The solar guider is the
small telescope on the upper right which receives sunlight from a small mirror adjacent to
the objective lens but not seen in the previous picture. This telescope was designed and
constructed by Douglas Martin shown the picture.
