Before looking through your telescope for the first time
Before you look at something for the first time, you must coordinate the viewfinder and the telescope lens.
You have to position the viewfinder 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 viewfinder to hone in roughly on objects
before you observe these objects magnified through the telescope eyepiece.

Coordinating the viewfinder and the telescope
Look through the telescope eyepiece (15) and hone in on a far away object that you can see well (for in-
stance, a tree). Focus in on the object with the focus knob in the way shown in Fig. 7a.
Note: The object must be located in the middle of your field of vision when you look through the telescope
eyepiece.
Tip: If you loosen the locating screws for the vertical fine adjustment (12) and the vertical 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 field of vision, you can retighten the locating screws and fix the position of the telescope.
Next, look through the viewfinder (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 viewfinder 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 viewfinder is not exactly in the middle of the crosshair (Fig. 7b),
then you must turn the adjusting screws for the viewfinder (3). Turn the screws until the image is positioned
in the middle of the crosshair (Fig. 7c). When you look through the eyepiece (14), you should now see the
same image detail as you see when you look through the viewfinder (but upside down of course).
Important: The viewfinder and telescope are properly matched only when both image sections are equal.
