To install the eyepiece onto the rear of the spotting scope (for land use):
1.
Unthread the cap from the rear cell.
2.
Thread the metal ring of the erect image diagonal onto the threads of the rear
cell.
3.
Remove the caps and loosen the thumbscrew on the diagonal so it does not
obstruct the inner diameter of the barrel
4.
Slide the chrome portion of the eyepiece into the eyepiece barrel.
5.
Tighten the thumbscrew to hold the eyepiece in place.

The C130 Mak comes with a 10x50mm finder.
finder is the power. The second number is the diameter of the objective lens in
millimeters. For example, the C130 Mak finder is 10x50 which means it is 10 power and has a 50mm objective lens. Incidentally, power
is always compared to the unaided human eye. So, a 10 power finder magnifies images ten times more than the human eye. The
finderscope is adjusted using the six adjustment screws located 120˚ around each finderscope ring.
The finderscope comes pre-assembled and is mounted inside the finderscope bracket rings. To attach the finderscope:
1.
Loosen the set screw on the mounting bracket on the spotting scope (see Figure 1-3).
2.
Slide the finder bracket (with finderscope attached) into the mounting bracket on the spotting scope.
3.
The finderscope bracket will slide in from the back. The finderscope should be oriented so that the objective lens is toward the
front end of the spotting scope.
4.
Tighten the set screw on the mounting bracket to hold the finderscope in
place.
Aligning the Finderscope:
To make things a little easier, you should align the finder during the day when it is
easier to locate objects. To align the finder:
1.
Choose a conspicuous object that is over 500 yards away. This will eliminate any
possible parallax effect.
2.
Point your spotting scope at the target and center it in the main optics of the
spotting scope (the eyepiece).
4.
Check the finder to see where the object is located in the field of view.
5.
Adjust the screws on the finder bracket, tightening one while loosening another, until the cross hairs are centered on the target.
Accurate alignment of the finder will make it much easier to find objects in the main optical tube. Remember that the finderscope is a
simple refracting telescope and therefore will always give an inverted (upside-down and backwards) view. Because of this, it may take a
few minutes to familiarize yourself with the directional change each screw has on the finder.

Your C130 can be mounted on either a photo tripod or an equatorial mount. The dovetail mounting bracket is compatible with many
equatorial mounts including Celestron's CG-5 and Advanced GT "Goto" mount. The mounting bracket also has two ¼"-20 threaded holes
to mount on to a photo tripod (#93596).
