Loosen both the dovetail-plate lock screw and safety screw until the tips of these screws no longer
extended into the inner part of the dovetail block. Slide the dovetail-mounted scope into the dovetail
mounting block of the mount and tighten the
dovetail lock screw (centered on the notch)
onto the dovetail tube plate until snug.
First tighten the dovetail lock screw, and then
tighten the small chrome safety screw onto
the dovetail mounting block until snug.
Change the position of the dovetail tube pate
on the VMC95L or VMC110L optical tube with
the supplied Allen wrench if you attach it onto a
Vixen mount other than the SKYPOD and PORTA .
1. Remove the dovetail tube plate from the
optical tube.
2. Attach the dovetail tube plate to the bottom
of the optical tube as shown in the figure.
3. Loosen both the dovetail-plate lock screw
and safety screw until the tips of these
screws no longer extended into the inner
part of the dovetail block. Slide the dovetail-
mounted scope into the dovetail mounting
block of the mount and tighten the dovetail
lock screw (centered on the notch) onto the
dovetail tube plate until snug.

ACCESSORY CHART
Photographic Configuration
Some of optional accessories shown in this chart will be needed if you take pictures with SLR
camera, digital camera or CCD video camera.
Eyepiece Focal length of telescope Focal length of eyepiece Magnification
NPL20mm 1035mm 20mm 52x
NPV 9mm 1035mm 9mm 173x
You may need an eyepiece sold
separately. The telescope does
not come with the eyepiece as
standard accessory unless you
purchased a package.
For the novice telescope user it is difficult to locate a selected object in the field of view at high
magnification. Using a finder scope will make this easier.

Magnification of the Telescope
When using an eyepiece with
short focal length (small number in
millimeters), the image will be dim
and the range of sharp focus will
be small. The image will be harder
to see so begin with an eyepiece
with long focal length. Dividing the
focal length of the telescope by
the focal length of the eyepiece
gives the magnification.
Example: Calculating the eyepiece magnification
of a telescope with 1035mm focal length (VMC110L).
