Adjustment of a paralactic mounting
Every paralactic mounting has two axes, which each
can be opened, moved and closed again. These are
the right ascension axis and the declination axis.
If you’ve adjusted and aligned the telescope
correctly, then the advantage of this paralactic
mounting is that you now can only track the celestial
objects through the fine movement with the shafts.
You can control the movement automatically
through
an
additionally
attached
motor
(available in Seben’s accessories program).
The adjustment of the mounting is important, because both axes have to stand level. This has the effect that
the telescope, no matter how it’s positioned, won’t tip over sideways due to the unilateral overload. Think of a
seesaw: if one side has more load on it, then it will sink downwards.
On the one hand this affects the tube, which has to be level in its telescope tube ring: it shouldn’t tip over
sideways when the axis is opened.
On the other hand it affects the axis of the tube and the weights. Also here, if the axis is opened, then neither
the tube nor the counterweight should drift off.
If now both sides have the same weight, like with a seesaw, then they are in balance and adjusted.
We’ll now explain you how to do that in detail.
We first adjust the right ascension axis. This axis
affects the tube and the rod with the weights.
First
bring
the
telescope
tube
and
the
counterweight in a horizontal position. Now you
can see if a side is heavier than the other and if it
slumps downwards.
