iOptron mounts: A new addition to the CEM family

April 4 2019, Stefan Taube

CEM series mounts from iOptron are already widely used in the US and are becoming increasingly well known in Europe too. The CEM25P mount for portable astrophotography with Newtonian telescopes of up to 6 inches aperture and the CEM60 mount for use in observatories have proved particularly popular.

With their new CEM40 and CEM40-EC with encoders, iOptron now provides a middle range mount capable of carrying loads of up to 18 kilograms. The CEM40 is hence ideally suited for astrophotography with telescopes of up to 8 inches (200 millimetres) in aperture.

The CEM40 is the latest addition to iOptron’s CEM series

The abbreviation CEM stands for centre-balance equatorial mount, i.e. for equatorial mounts which are supported at their centre of gravity. This design ensures an excellent relation between weight and carrying capacity. The CEM40 weighs only 7 kilograms and yet can carry OTAs up to 2.5 times heavier. The amazing carrying capacity of CEM mounts has been constantly reaffirmed by our customers – especially regarding the CEM25P.

The CEM40 comes equipped with an electronic pole finder, known as ‘iPolar’. A laptop is required to operate this however, so the CEM40 is particularly suitable for astrophotographers who already use a laptop for their camera. iPolar and built-in GPS provide easy and accurate alignment and GoTo computer control initialization.

The encoders installed in the CEM40-EC version ensure very high GoTo accuracy and allow worm gear permanent periodic error correction – a problem that all mounts suffer from. The CEM40-EC does away with the need for guiding with your astrophotography.

The CEM family now covers a wide range of load carrying capacities, offering a suitable model for every budget!
