The installation method described here is the same for both .96" and 1-1/4" accessories.
Using Your C90 Visually
With the standard accessories attached, you are ready for your first look.
1.
Point your C90 at a distant object.
2. Locate the object in the finderscope. The finder is mounted and aligned at the factory. If the
alignment is not accurate, realign the finderscope by following the instructions on the next
page.
3.
Center the target on the cross hairs by adjusting the tripod controls.
4.
Look through the C90 and center your target.
Repeat this process for each object you observe.
Focusing
To focus, turn the focus ring on the C90 tube until the image is sharp. On the rubber covered C90, turn the
front portion of the lens to focus. For objects closer than the one you are currently observing, turn the
focusing ring clockwise and for objects further away, turn counterclockwise. The C90 has a tremendous
amount of focus travel to allow for critical, sharp focusing.
Changing Eyepieces
You can vary the power of your C90 spotting scope simply by changing eyepieces (purchased separately).
To change eyepieces:
1.
Loosen the thumbscrew on the 45° Erect Image Diagonal.
