3. Adjustment of the viewfinder.
The viewfinder, whether optical with crosshairs or as a red dot finder, naturally has to be aimed at the same
point in the sky as the telescope itself, otherwise the objects in the sky cannot be found. Proceed as follows:
Set up the telescope on a bright day in such a way that you can aim the telescope at a very distant
object, such as a church spire, electricity pylon or something similar.
There should be a good few kilometres between the object and your telescope.
Install the eyepiece with the longest focal length available into the focuser of the telescope. Now
release the axis clamps – after all, the system is balanced – and aim the telescope at the chosen
distant object.
To do this, simply take a bearing with your eye along the tube and as soon as the prominent point in
the landscape appears to contact the upper edge of the tube, clamp the axes again.
Please never fasten too tightly. Now position the object in the middle of the eyepiece field of view using the
manual fine focus adjustment knobs. This all takes place without the use of any possible motorised tracking.
With a red dot finder, a red dot is visible and not the crosshairs. With a red dot finder, the image is not upside
down, as it has only a transparent projection surface and no lenses.
3.1. Optical finder.
Most optical finderscopes have a permanent compression spring (A) and two adjustment screws (B).
Adjustment is completed within seconds.
3.2. Red dot finder.
At the front of the red dot finder is the adjustment wheel (E) for the horizontal adjustment, i.e. the azimuth. At
the rear end is an identical adjustment wheel for the elevation axis (D). These allow the red dot finder to be
adjusted precisely.
(C in this case ON/OFF switch and dimmer)
Attention:
Never use the telescope to look at the Sun! Concentrated sunlight causes serious eye damage. Children may only
use the telescope under adult supervision.
