 ^ 10    | Before using the telescope you have to tare the rotation axes. First lose the clutch knobs fixing the right-ascension axis, until you can freely move the telescope around this axis. Now adjust the position of the counterweight such that there is no movement along this axis anymore. Tighten the clutch knobs again and repeat this procedure for the declination axis. As there are no counterweights for this axis, one has to shift the tube along the clamp to tare the declination axis.    |   {{ost:c8:IMG_7108_small.jpg?300}}  | {{ost:c8:011_resize.jpg?300}}  | ^ 10    | Before using the telescope you have to tare the rotation axes.
