The Basic Components; Of Your Telescope; Tripod Legs - Orion Observer 60 Instruction Manual

3. the Basic components of Your telescope
Figure 1 shows the fully assembled Observer 60 . All the major components of the telescope are described and numbered to help
you identify each part and understand its use. Refer back to this figure when assembling the telescope.
1
optical tube
This is the main optical component of the telescope. The
glass lens at the front of the tube gathers incoming light
and focuses it by bending (or refracting) the light rays.
The tube assembly has several parts built into it, which
are shown and discussed in detail in the next section.
2
90° Mirror star diagonal
The diagonal contains a mirror that reflects the light gath-
ered through the optical tube to the eyepiece. The
diagonal is angled to allow you to view objects that are
high in the sky from a comfortable position.
3
25mm Kellner eyepiece
The eyepiece is the part of the telescope that you actu-
ally look through to see things. The focal length of the
eyepiece and the telescope determines the magnifying
power of the telescope. Magnification is discussed in
more detail in the Using Your Telescope section.

EZ Finder ii reflex sight
tM
This is a special "finder" that helps you aim the telescope
and locate objects in the sky for close-up viewing with
your telescope. The EZ Finder II generates a red LED
"dot" that shows where your telescope is aimed. The
use of the EZ Finder II is discussed in the Getting
Started section.
5
"Yoke" altazimuth mount
The mount couples the telescope to the tripod and allows
you to move the optical tube easily both up -and-down
and right-and-left.

tripod legs

These aluminum tripod legs support the telescope and
keep it steady. They can extend from 27" to 50" long.
7
accessory tray
This tray is a convenient place for holding extra eyepieces
and other small pieces of equipment.
