Attaching Diagonal and
Eyepiece
The eyepiece holder (#15,
Fig. 8) threads directly
onto
the
rear-cellthread
of the
8'
and
10' telescopes. The
diagonal prism (#13, Fig.8)
slides into the eyepiece holder and, in turn, accepts
the
supplied
1-114"
O.D.
eyepiece. For
astronomical observations,
the diagonal prism generally provides
a
more
comfortable
right-angle
viewing position.
Alternately, an eyepiece may be inserted directly into the eyepiece holder for
straight-through observations. Note
in
this case, however, that the image will
appear inverted and reversed
left-for-right. With the diagonal prism, telescopic images
appear correctly oriented
up-and-down,
but
still
reversed
left{or-right.
For
terrestrial applications, where
a
fully corrected image orientation is desired,
both
up-and-down and left-for-right, the optional#924 Erecting Prism
('l-114'O.D.)
should
be
ordered separately.
Eyepieces and the diagonal prism are held
in their
respective places on the telescope by a
moderate
tightening of the thumbscrews
on
the diagonal prism
and
eyepiece
holder.
