4. Testing. Place the finder and fix it to its plastic base (that has been
previously fixed to the telescope). Use the two thumbscrews (#2) to
fix it tightly to the base (#4).
Turn ON the finder by rotating the ON/OFF button (#1).
A loud "click" is heard when switching to ON or OFF. Rotate it to its
maximum position to obtain the maximum brightness of the circles.
Peek through the glass window where the reticule is projected (#5) as shown.
The red circles are ONLY visible from one direction (as shown) and in a dark
environment! These kinds of finders cannot be used during the day!
Make sure you see three red circles.
It is important to mention that the circles will only be visible in a dark
environment. We recommend conducting this test indoors in a low illuminated
room. Use the ON/OFF and brightness button (#1) to adjust and to familiarise
yourself with the brightness settings and how the finder works.
5. How do the circles look like?
There are three circles with different angular sizes of 4°,
2° and 0.5°. They are important to determine an object's
relative size and angular distance.
The reticules are used to locate objects in the night sky,
but before that it is necessary to align the finder with the telescope.
6. How to align it to the telescope?
STEP 1.
As mentioned previously, this alignment procedure should be done in a dark environment or during the night. Only this
way can one see the red reticule. Turn ON the finder and set it to its maximum brightness (use new batteries).
STEP 2
Select a low power eyepiece. Point the telescope to a distant land object, easy to recognise, like a church tower. Centre its
pinnacle or a distinct feature into the eyepiece's centre of view.
STEP 3
Peek through the glass window where the reticule is projected (#5) and compare the reticule's position to that of the
telescope (some telescope configurations and designs may invert or mirror the seen image). We want to make sure that
the smallest circle is centred to the previous selected object as seen through the telescope.
Initially this circle should be way off, and just by chance will it be centred to the object. To centre it, use the three
alignment thumbscrews (#7). Each will displace the red reticules in distinct trajectories 120 degrees apart. Get used to see
which direction each one moves. Adjust as necessary. As soon as the circles match the object as seen through telescope -
alignment is successful. Repeat if necessary for each observing session.
