Mount Specifications
Mount Head
Counterweight Bar
Right Ascension (R.A)
Declination (DEC)
The mounting block is designed to attach an optical tube with dovetail
tube plate (or dovetsail slide bar). The optical tube is firmly fixed with
both the lock screw with large grab knob and safety screw. This allows
quick set up and removal of the optical tube.
The optical tube mounted on the
equatorial mount has to be balan-
ced with a counterweight to use the
equatorial mount properly.
If the AP mount is set to be aligned with one rotational axis parallel to the
Earth’s axis, th e motion of R.A will follow th e motion of stars.
If the AP mount is set to be aligned with one rotational axis parallel to
the Earth’s axis, the motion of DEC will be angled to the motion of the
R.A.
