9) Case: The Tele Vue-60is case is fitted for the

telescope with a DSLR camera attached. When

packing the scope in the case be sure to place the

rigid ethafoam filler over the scope’s objective.

The top two screws in the mount ring will protrude

through the aperture in the ethafoam.

CARE:

The Tele Vue-60is requires no special care. Treat

it as you would any fine camera lens. Use the lens

cap when the telescope is not in use.

If you leave your scope idle in dewy condi-

tions it is always a good idea to tilt the telescope

slightly up. If dew forms on the lens during cold

weather, it is best to use an electric hair dryer (on the lowest setting) to gently warm it away. A few specks of dust will

have no effect on the quality of the image, and may be gently blown off with a squeeze bulb.

Fingerprints should be cleaned off. Though the anti-reflection coatings are durable, they can be scratched. The

simplest cleaning method is to moisten a very soft, lint-free tissue, cloth, “Q-Tip” or surgical cotton with a lens or glass

cleaner and gently whisk away the stain. Do not apply any solutions directly to the glass surfaces. After every cleaning

stroke use a fresh applicator. The fewer strokes the better! Any residual “film” will not effect visual performance.

The star diagonal has a first-surface mirror. It should be cleaned only when absolutely necessary. The Tele Vue

60° and 90° diagonal mirror should be removed for cleaning by removing the back cover's four screws, lifting the back

off the diagonal body and cleaning the entire mirror surface. First blow loose dust away with a squeeze bulb.
