Celestron ALT AZ Telescope Mount with Tripod and Slow Motion Controls. Crack in one leg at extender but usable. Please see photos for details.
Celestron AZ3 - Alt-Azimuth Mount with manual slow-motioncontrols and with tripod, 5 kg payload.
This mount is ideal for nature observing as well as for\"grab and go\" astronomical observing.
Both axes have a manual slow-motion control through flexibleshafts. This allows you equally well to track a bird in mid-flight, to track aboat on the horizon or a celestial object while it moves across the night-sky.Tracking can be done comfortably and with good precision, so extended visualobserving is possible even with high magnifications.
The AZ3 mount comes with a sturdy but light-weight aluminumtripod - adjustable in height from 71 cm (tripod height approx. 28 inches + 6 inches for ALT AZ head) to 123 cm (tripod height approx. 48 inches + 6 inches for ALT AZ head). The mount can carry instrument weights up to approximately 5 kg (approx. 11 pounds). The AZ3 itself weighs approx. 4.6kg (approx. 10 pounds) including the tripod.
The AZ3 can be pointed at any point between the horizon and almost up to the zenith. In azimuth it allows for a 360° movement.
Includes AZ3 Camera Thread Adaptor - for the attachment of instruments with 1/4\"-20 camera thread to the AZ3. Small telescopes, spotting scopes, cameras and many other instruments usually have a 1/4\" cameratripod thread.
Practical tip from TS: How to balance the mount?
For nature observing where you point the instrument at thehorizon you usually do not need to do anything to balance the instrument on themount. The instrument should already be well balanced on top of the AZ3.
If you need to point the mount upwards, such as for watchingbirds in flight or for astronomy, you should proceed as follows:
1. Attach the instrument to the AZ3 and loosen the screw that locks the altitude movement until the mount moves very easily in altitude.
2. Move the mount until the instrument points 45° above the horizon. (For astronomers: You can point it at Polaris. In typical moderate regions such as in most parts of Europe the polar star is roughly 45-50° abovethe horizon.)
3. Move the telescope further forward in its tube rings (if availble), or use adjustable Arca Swiss plate (if availble) until the mount is properly balanced while it still is pointed 45° upwards.
4. Point the instrument at the horizon. The telescope will have a tendency to pan forward, so tighten the altitude screw again until it just doesn´t move on its own accord.
While pointing the telescope at the horizon there will now be a slight imbalance. At the same time there will be a slight imbalance in the other direction if you point the telescope at the zenith. However, on average the imbalance is now small enough in either direction to not cause any problemsin actual use.
