Section 4 - THE TELESCOPE<br />
General Features<br />
TABLE OF CONTENTS<br />
The CFH telescope is of the yoke type similar to the Palomar 5 meter telescope. It is a classical<br />
Prime Focus/Cassegrain<br />
combination. The primary mirror has a usable diameter of 3.58 m and has a parabolic figure. The<br />
primary and secondary<br />
mirrors are made of the low expansion coefficient glass-ceramic "Cer-Vit" and are thus practically<br />
immune to thermal distortion.<br />
