Package Consisting of :
Basics of Equatorial Mounts
CAUTION
Basic movement of the AXJ Mount
The AXJ Equatorial mount package contains the items listed below. Check if all the items are included.
Note:
* Your AXJ mount package may differ when you purchase it as a complete
telescope package.
* A power supply unit is sold separately.
What is an Equatorial Mount?
In the northern hemisphere, stars appear to turn around the polar star (the north celestial
pole) making approximately one rotation per day. This is called diurnal motion and occurs
because the earth turns on its own axis once a day. The equatorial mount is a platform
which is designed to rotate parallel to earth‘s rotational axis.
Every movement of the electrically driven AXJ Mount is fully controlled by the STAR BOOK TEN hand controller. The mount will perform smooth and
accurate movements when each component on the mount is balanced correctly. An unbalanced mount may cause vibrations and can result in tracking
errors or failure of rotational mechanisms. Make sure that the telescope is well balanced.
Do not rotate the mount manually without loosening the clamp levers.
The AXJ mount has clamps which allow you to rotate the Right Ascension (R.A.) and Declination (DEC.) axes freely for quick set up and compact
storage of the mount. Remember to tighten the clamp levers when you usethe mount. The clamp levers should be loosened to protect the inner gear
train for storage and when you transport the mount.
Never connect the STAR BOOK cable to other equipment such as a PC. This could result in electrical shock, fire, or damage to the equipment. (The
specifications of the STAR BOOK cable are not compatible with RS232C connectors.)
Be careful not to bang the mount against other objects. This could damage the gears and bearings.

1Loosen the R.A. clamp lever while holding the counterweight
bar (1-1) and turn the telescope tube until the DEC. axis comes
to horizontal (1-2). Tighten the R.A. clamp lever and loosen the
DEC. clamp lever. Be sure to hold the optical tube or counter-
weight in hand while loosing the clamp levers.
2Release the telescope gradually to see which way the telescope rotates around the declination axis.
If the telescope tube starts rotating as you release, it shows there is an imbalance in DEC.
To determine the balance point, loosen the lock screw that hold the telescope tube to the dovetail-plate
mounting block and slide the telescope tube either forward or backward until it remains stationary.
3Tighten the lock screw (and the safety screw) securely to hold the telescope tube in place.
4Tighten the DEC. clamp lever to finish this adjustment.
1Loosen the R.A. clamp lever while holding the counterweight bar (1-1) and turn the telescope tube until the DEC. axis comes to horizontal (1-2). Tighten
the R.A. clamp lever and loosen the DEC. clamp lever. Be sure to hold the optical tube or counterweight in hand while loosening the clamp lever.
2Release the telescope gradually to see which way the telescope rotates around the declination
axis. If the telescope tube starts rotating as you release, it shows there is an imbalance in DEC.
To determine the balance point, loosen the tube ring lock knobs that hold the telescope tube and slide
the telescope tube either forward or backward until it remains stationary.
3Tighten the tube ring lock knobs (and the safety screw if any) securely to hold the telescope tube in place.
4Tighten the DEC clamp lever to finish this adjustment.
CAUTION
CAUTION
Do not loosen the lock screw too much in balancing. This could drop off the telescope tube or lead to injury.
Pay close attention to the security of the telescope tube when you balance the mount.

1Loosen the R.A. clamp lever while holding the counterweight bar and turn the telescope tube until the DEC axis comes to horizontal as shown in
the figure. Release the telescope tube gradually to see which way the telescope rotates around the R.A. axis. If the telescope tube starts moving by
its own weight as you release, it shows there is an imbalance in the R.A.
2While holding the counterweight bar, loosen the lock knob on the counterweight so that it can be moved
to a point where it balances the telescope tube. This is the point at which the telescope remains stationary
when the R.A. clamp lever is loose.
If your telescope is light in weight, the mount may balance without the supplied counterweight.
(The extended counterweight bar itself can act as a counterweight.) Retract the counterweight
bar for further balance adjustment.
3Tighten the lock knob on the counterweight to hold in place.
4Tighten the R.A. clamp lever on the mount securely.

Tips on Proper Balancing
With balance arrangements below, the AXJ mount can balance a counterpart weighing stated below on condition that the center of gravity of the counter-
part is given at a distance of 25cm from the intersection of the R. A. and DEC axes. The less the distance of the counterpart from the intersection, the
more the allowable loading weight of the counterpart.
No counterweight: A 1.5kg (3.3 lb.) & a 3.5kg (7.7 lb.) counterweights:
A 7.0kg (15.4 lb.) counterweight:
A 1.5kg (3.3 lb.) counterweights:
A 3.5kg (7.7 lb.) counterweights: A 3.5kg (3.3 lb.) & a 7.0kg (7.7 lb.) counterweights:
