Practical tip from TS - how can I get the telescope into balance:
For completely using the full stability of the mount, it is important to balance the telescope as well as possible. Proceed as follows:

1. Slide the counterweigt to a lower position of the counterweigth shaft and unlock moth axes of the mount (right ascension and declination axis).

2. Turn the telescope to a horizontal position. Then, move the telescope tube in the direction of the focuser or main optics until the tube is balanced.

3. Rotate the RA axis until the counterweight shaft is horizontal. Now, slide the counterweight until telescope and counterweight balance each other out.

Now the telescope is balanced and you can start.

Practical tip from TS - how many counterweights:
We recommend not to put the counterweight at the lowest end of the counterweight rod. The disadvantage lever causes vibrations. If the balance can only be achieved by placing the counterweight to the lowest end, it is better to use a heavier or an additional counterweight. By this, you can place the counterweigth at a better position, so vibrations are reduced.
