Leica Standard Viewing Tube – Separated Eyepieces

2. Lock the eyepieces into the eyetubes by

tightening the silver screws on the under-
side of the eyetubes with a standard Cross
type (Phillips) screwdriver (not provided).

The eyepieces will still rotate, but they
will be captive in the eyetubes.

The standard viewing tube has a rotat-
able dovetail. Therefore, you can now

rotate the standard viewing tube freely in any
orientation.

1. Insert the eyepieces into the eyetubes.

Standard viewing tube; eyetubes do not yet
contain the eyepieces
