Assembly
This section covers the correct set up and operating procedures for your Celestron
C5 spotting scope and includes information on visual and photographic
observations. The C5 spotting scope uses a combination of mirrors and lenses to
produce an image. Such an optical system is known as a compound lens. This
particular design, known as a Schmidt-Cassegrain, is one of the most compact
and rugged optical systems on the market today. The C5 (#52219) comes
standard with the following accessories:
· 25mm Plossl Eyepiece 1.25” (48x)
· 6x30 Erect Image Finderscope
· 45° Erect Image Diagonal - 1.25”
· Photo Tripod Adapter block
· Nylon Water Resistant Case
· Lens Cap
The Erect Image Diagonal
The diagonal is a prism that diverts the light at a right angle from the light path of
the spotting scope. The C5 spotting scope comes with an erect image diagonal
that is designed for terrestrial viewing. To attach the diagonal:
1. Turn the thumbscrew on the visual
back until its tip no longer extends
into (i.e., obstructs) the inner
diameter of the visual back.
2. Slide the chrome portion of the
diagonal into the visual back.
3. Tighten the thumbscrew on the
visual back to hold the diagonal in
place.
If you wish to change the orientation of
the diagonal, loosen the thumbscrew on the visual back until the diagonal rotates
freely. Rotate the diagonal to the desired position and tighten the thumbscrew.
