Equatorial Mount
The equatorial mount allows for the telescope's axes of
rotation to be adjusted to the user's latitude. The overall
effect is that the observer can track the heavens along
the path of the Earth’s rotation.
Eyepiece
The part into which you look. It has a number of lenses
which magnify and allow your eye to focus on the image
formed by the telescope. Two eyepieces are supplied
with the telescope. You can buy additional eyepieces;
eyepieces of different focal lengths will produce different
magnification factors.
Finder scope
Aids in pointing the telescope. It is a small, low-power
telescope with “cross hairs” that attach to the optical tube.
Its wide field of view greatly reduces the work of finding a
faint object in the main eyepiece of the telescope.
optical tube
The main body of the telescope, holding the optics.
Primary Mirror
The large curved optical mirror located at the bottom of
the optical tube.
Primary Mirror cell
The mechanical holder for the primary mirror, with align-
ment adjusting bolts which allow exact positioning of the
tilt of the primary mirror.
rack and Pinion Focuser
The mechanical holder for the eyepiece, which allows the
eyepiece to be moved in and out to adjust the focus of
the telescope.
secondary Mirror
The small elliptical-shaped flat optical mirror located
inside the optical tube below the focuser. It diverts light
sideways to the focuser.
secondary Mirror Holder
The mechanical holder for the secondary mirror.
A three-vane spider is used.
