Lens Cap
Assembly
To attach the Erect Image Diagonal and an Eyepiece:
1. Remove any caps from the rear of the optical tube, the erect image diagonal, and the eyepiece.
2. Loosen all thumbscrews on the rear part of the optical tube and the erect image diagonal so that the threads do not protrude into the barrels.
3. Slide the chrome portion of the erect image diagonal into the rear of the optical tube as shown in the left image below. Then, tighten the
thumbscrews to hold the erect image diagonal in place.
4. Slide the chrome portion of the eyepiece (use the 32 mm) into the erect image diagonal (see right image below). Then, tighten the thumbscrew
to hold the eyepiece in place.
5. To use other eyepieces of varying powers, reverse the installation of the eyepiece above and install other eyepieces. Any 1.25" eyepiece will
work with this spotting scope. Celestron offers a wide selection of optional eyepieces.
To attach the 8x21 Erect Image Finderscope:
The finderscope is an aid to locating objects to view as it is an 8 power instrument with a much wider field of view than the spotting scope itself.
The finderscope itself comes pre-assembled and is mounted inside the bracket of the finderscope.
1. Loosen the thumbscrew on the mounting bracket on the optical tube (left image below).
2. Slide the finder bracket (with finderscope attached) into the mounting bracket on the optical tube (center image below).
3. The finderscope bracket will slide in from the back. The finderscope should be oriented so that the objective lens (larger piece of glass) is toward
the front end of the spotting scope.
4. Tighten the thumbscrew on the mounting bracket to hold the finderscope firmly in place. The finderscope is correctly attached as shown in the
right image below.
