Getting Started
Focusing the Finder Scope
The 8X50 Correct Image Finder Scope has focusing adjustments for the objective and the eyepiece. You can make the initial focus
adjustments hand held:
1. Loosen the eyepiece focus adjustment by turning it counterclockwise while firmly holding the eyepiece focus lock ring (
1,
Fig. 2
). Further separate the eyepiece focuser (
2, Fig. 2
) and the focuser lock ring to allow a good range of adjustment.
2. Aim the finder scope at a blank wall and concentrate your eye on the crosshairs. Turn the eyepiece focuser (
2, Fig. 2
) left
or right until you see the finder scope crosshairs perfectly sharp.
3. Once you have found perfect crosshair focus, turn the eyepiece focuser lock ring (
1, Fig. 2
) against the eyepiece focuser
(
2, Fig. 2
) until it is snug so that it holds the eyepiece focus position.
4. Loosen the objective lens focus adjustment by turning it counterclockwise while firmly holding the objective lens focus lock
ring (
1, Fig. 3
). Further separate the objective lens focuser (
2, Fig. 3
), and the focuser lock ring to allow a good range of
adjustment.
5. Aim the finder scope at a very distant object (the greater the distance the better) and concentrate your eye on the distant
object. Turn the lens objective focuser (
2, Fig. 3
) left or right until you see the distant object and the crosshairs of the
finder scope perfectly sharp.
6. Once you have found perfect focus, turn the objective lens focuser lock ring (
1, Fig. 3
) against the focuser until it is snug
so that it holds the focus position.
7. Repeat this process on a bright star or the Moon, once you have attached the finder scope on the telescope (see below) to
get perfect focus adjustment for astronomy.
