The Eyepiece

The eyepiece is the optical element that magnies the image focused by

the telescope. The eyepiece ts into either the visual back directly or the

star diagonal. To install the eyepiece:

1. Loosen the thumbscrew on the star diagonal so it does not obstruct

the inner diameter of the eyepiece end of the diagonal.

2. Slide the chrome portion of the eyepiece into the star diagonal.

3. Tighten the thumbscrew to hold the eyepiece in place.

To remove the eyepiece, loosen the thumbscrew on the star diagonal

and slide the eyepiece out.

Eyepieces are commonly referred to by focal length and barrel diameter.

The focal length of each eyepiece is printed on the eyepiece barrel.

The longer the focal length (i.e., the larger the number) the lower the

eyepiece power or magnication; and the shorter the focal length

(i.e., the smaller the number) the higher the magnication. Generally,

you will use low-to-moderate power when viewing. For more information

on how to determine power, see the section on “Calculating Magnication.”

Barrel diameter is the diameter of the barrel that slides into the star

diagonal or visual back. The CPC uses eyepieces with a standard 1-1/4”

barrel diameter.

The Finderscope

The CPC telescope comes with a 9x50 nderscope. The specications

for a nderscope stand for the magnication and the aperture, in

millimeters, of the scope. So, a 9x50 nder magnies objects nine times

and has a 50 mm objective lens.

Finderscope Installation

The nderscope must rst be mounted in the included quick-release

bracket then attached to the rear cell of the telescope. To install

the nderscope:

1. Locate the nderscope mounting bracket attached to the bottom

portion of the nder bracket. Loosen the two thumb screws to slide

the mounting bracket from the nderscope bracket.

2. Find the two holes in the rear cell of the telescope on the top left,

when looking from the back of the tube.

3. Place the mounting bracket over the two holes of the rear cell as

shown in the gure 3-7.

4. Insert the screws through the bracket and into the rear cell.

WARNING: If you remove the mounting bracket, do not

completely thread the screws back into the rear cell of the

telescope. The screws may be long enough to obstruct the

movement of, and possibly damage the primary mirror.

With the bracket rmly attached to the telescope, you are ready to

attach the nder to the bracket.

1. Slide the O-Ring over the back of the nderscope and position it on

the tube toward the objective end of the nderscope.

2. Slide the eyepiece end of the nderscope into the front ring of the

bracket (the front ring is the one without the adjustment screws),

then through the back ring. It may be necessary to push down the

spring loaded pivot screw so that the nder will pass through the back

ring (see gure 3-6).

3. Push the nder back until the O-Ring is snug inside the front ring of

the nder bracket.

4. Hand tighten the two adjustment thumb screws until they make

contact with the nderscope.
