Focus Adjustment

(Ffg. 82)

1. Camera focusing is done using the binocular section of the trinocular

observation tuba.

* Whenever you remove the focusing telescope from the camera

unit be sure to install the dust cap.

2. Insert a finder eyepiece into the right eyepiece sleeve.

3. The finder eyepiece has a built-in focusing tens with four masks and

a double crosjline. and the focus is practically the same for the focusing

lens and the camera film plane. The masks indicate the areas covered,

and the numerals next to the masks correspond to the magnification

of the photo eyepiece. Different finder eyepieces are available for afferent

cameras. Select the type that is appropriate for the camera being used.

4. Because of the great depth of focus of 1.25X to 4X objectives, use

of the focusing magnifier (OFT) is recommended for accurate focusing.

O When using low power objectives, focusing may be accomplished

easier usmg the focusing telescope on the camera unit rather than the

finder eyepiece.
