4.2.1.
A distant object is centered at the telescope’s
field of view. In this example we have a house with a
chimney. The chimney is the reference point to place
at the center of the field of view. We first look
through the telescope with the lowest magnification
possible (H20mm should be preferrable). So we have
the widest field of view.
4.2.2.
Looking through the finderscope we see the
same building but in this case the chimney is not
centered. We adjust the finderscope using the three
thumbscrews so that the finderscope moves slightly.
This is enough to correct the objects position in the
finderscope. Trial and error is required to get a
satisfactory result. Make sure to tighten the 3 screws
after finishing so that the finderscope tube does not
move.
4.2.3.
After playing with the three findercope
thumbscrews and some trial and error we get the
finderscope recticle close to the center (in this case
the chimney). The Finderscope is now ready to use!
