Now with Dec. lock released,
loosen the tube ring lock clamps
and slide the OTA forward or back
in the tube rings until balanced.
Fix the tube and the Dec.axis.
repeat balancing each time when
placing additional accessories on
the telescopic tube, such as photo
and video cameras, eyepieces,
guides and other devices, which
enlarge the weight of the OTA.
Keep in mind that if the telescope
is not balanced properly, the clock
drive periodic error will increase.
Place the crosshair (2) into the
eyepiece f’=25mm (1) and then
insert the eyepiece in the focuser
tube (3).
Point the telescope at the distant
object (at least 400meters/yards
away), and then center it in the
teles-copic field of view using the
reticle. Fix telescope in this position
with the R.A. and Dec. locks.
AlIGNING tHE FINDEr SCOPE
High magnification of the main telescope makes it difficult to find a
required celestial object in the sky because of the small field of view.
This is why the telescope is equipped with a low-power finder scope
with a wide field of view. The finder scope makes it easier to locate
the object you want and then to observe it in the field of view of the
telescope. However, for the proper use of the finder scope, it must
be aligned with the main telescope, so that both the finder scope and
the telescope point at the same position in the sky.
