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, so we have the widest field of view.
4.2. When 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’s recticle close to the center (in
this case the chimney). The finderscope is now
ready to use!
