WD-17 Harmonic Mount

For observing, the tube weight should not exceed the mount’s maximum payload. For a stable photographic combination of tube and mount, it is wise to also pay attention to the tube length and dimension, where appropriate, to stay below the maximum load, as the leverage effect on the mount must be taken into account.

The counterweights are not taken into account when specifying the total weight, as the number of weights required depends on the optics used.
