4. How to use and how to align the finderscope?
4.1.
A distant object is centered at the
telescope’s field of view with an eyepiece. 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 (PL25mm should be preferrable). So we
have the widest field of view.
4.2.
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.
4.3.
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!
