The iOptron iO7102 CEM25 GoTo mount carries heavy telescopes and offers better vibration behavior through more favorable leverage.
♦ Excellent for astrophotography

♦ Carries telescopes up to 13 kg dead weight

♦ High quality stepper motors for accurate tracking and positioning with low power consumption

♦ Very low periodic screw error below +/- 10 arc seconds

♦ Also possible without Polarstern - illuminated pole finder included in delivery

♦ Go2Nova 8408 GoTo controller

♦ Vixen-level quick release for telescopes

♦ ST-4 autoguiding connection

♦ Including hard case and field tripod


iOptron CEM25 GoTo mount with tripod and case
The new mount design from iOptron offers more rigidity and less susceptibility to vibration, but at the same time more compact dimensions. All functions of a "normal" German mount are retained. The CEM25 is equipped with the sophisticated GoToNova control, with over 59,000 items in the data memory, large heated LC display and of course all the equipment features for astrophotography, such as P.E.C or autoguiding connection.

The CEM25P has very little periodic screw error. iOptron guarantees a value of less than +/- 10 arc seconds. This is achieved through improved product control and reduced manufacturer tolerances.
