Abstract
The requirements for a telescope mounting are divided into two distinct sections. The first is the set of mechanical components that are required to hold the optics of the telescope in their correct relative positions, and allow them to be collimated and focused. This section is normally called the telescope tube, and reference is made to it in Chaps. 1, 2, 3, and 8.

Notes
- 1.
Dove prisms have a trapezoidal cross section. Light entering one of the sloping faces is refracted down to the base of the prism, where it is reflected. After refraction at the second sloping face, the light beam emerges with an unchanged direction. Rotating the prism causes the light beam passing through it to rotate at twice the prism’s speed.

A liquid mirror telescope uses a rotating bath of mercury as its primary mirror. NB mercury and its compounds are highly poisonous – do not attempt to make such a telescope yourself.
