7.1 Diagonal Eyepiece (SB14)

The Diagonal eyepiece can be attached to the telescope for convenience in observing the zenith or when in confined spaces.

<Installation>

1Turn the telescope eyepiece ring counterclockwise to remove the eyepiece.

Be sure to hold the eyepiece, securely, so that you do not drop it. Attach the diagonal eyepiece to the telescope by reversing

the procedure.

The diagonal eyepiece can be rotated through 360°.

When sighting through the telescope with the diagonal eyepiece attached, the reticule may be seen deflected vertically or horizontally, but this has no influence upon accuracy.
