Before looking through your telescope for
the fi rst time
Before you look at something for the fi rst
time, you must coordinate the fi nderscope (2)
and the telescope (1). You must position the
fi nderscope in such a way that you see the
same thing through it as you do through the
eyepiece of the telescope.
This is the only way you can use your fi n-
derscope: to hone in coarsely on objects
before you observe these objects magnifi ed
through the telescope eyepiece.
Coordinating the fi nderscope and the
telescope
Look through the eyepiece (14) of the te-
lescope (1) and hone in on a far away object
that you can see well (for instance, a church
tower). Focus in on the object with the focus
knob (7) in the way shown in fi gure 10.
Important: The object must be located in the
middle of your fi eld of vision when you look
through the telescope eyepiece.
Tip: If you loosen the screws for the vertical
fi ne adjustment mechanism (12) and the ver-
tical axis (13), you will be able to move the
telescope (1) to the right and left, up and
down.

When you have the object well placed in your
fi eld of vision, you can retighten the locating
screws and fi x the position of the telescope.
Look through the fi nderscope (2). You will see
the image of the object you honed in on in the
crosshairs. The image will be upside down.
Note: The image you see through the fi n-
derscope is upside down because the lenses
are inverting it. This is completely normal, and
not an error.
If the image you're looking at through the fi n-
derscope is not exactly in the middle of the
crosshairs (Figure 11a), you must turn the
adjusting screws for the fi nderscope (3). Turn
the screws until the image is positioned in the
middle of the crosshairs (Figure 11b).
When you look through the eyepiece (14),
you should now see the same image detail as
you see when you look through the fi ndersco-
pe (but upside-down of course).
Important: Only when both images are the
same are the fi nderscope and the telescope
coordinated.
