iOptron CEM40 GoTo Mount with LiteRoc Tripod

Find out more about the CEM series...

The CEM40 is the latest mount in iOptron's Center-Balanced Equatorial Mount (CEM) series.

The mount weighs only 7.2 kilograms, yet it can carry optical instruments and accessories up to 18 kilograms. This excellent payload-to-weight ratio of 2.5 is why the CEM40 is so versatile. You can take it to the best observation sites under dark skies or install it on a small pier in your home observatory.

But the mount has even more advantages:

• The integrated iPolar electronic polar finder makes perfectly aligning the mount to the north a breeze, even when the North Star is not visible! Note: a laptop or PC is required to use the iPolar.
• The large levers allow you to disengage the RA and Dec gears to move the axes freely, even while wearing gloves.
• The internal cable management prevents tangles and breakage.
• The newly designed self-centering universal saddle accepts standard Losmandy and Vixen dovetail bars and provides precise alignment of your optics.
• The CNC-machined mount body not only looks elegant but is also durable.

The GoTo computer control includes the modern Go2Nova 8407+ hand controller, which incorporates a heater so the display does not fog up due to condensation. The database contains over 212,000 objects! In addition, the controller is equipped with a 32-channel GPS, which saves you the hassle of entering the date, location, and time. Of course, the mount has an ST-4 port for autoguiding.

In addition to the special design of the CEM, the movement of the axes is a special feature of this mount. The very quiet axis movement with stepper motors is ideal for balcony observatories and consumes relatively little power.

The CEM40 is a very versatile and advanced mount!

With or without encoders: the mount is available in two versions, both of which track your optics precisely across the night sky. The version with high-resolution encoders (EC) on both axes achieves a precision better than 0.25 arcseconds and corrects the periodic error of the worm gear in real time! This eliminates the need for guiding in astrophotography.

The LiteRoc tripod is a new tripod developed by iOptron that is as light as possible but as stable as necessary. It is therefore very well suited to portable mounts for mobile observatories and astrophotographers. Compared to the previous version, the LiteRoc tripod has a more stable support for the extendable tripod legs and larger clamping levers. The upper tripod legs have a diameter of 45 mm (1.75") and the lower section 38 mm (1.5"). This makes the extendable legs just as strong as those of the previous 2" tripod. Thanks to the narrower design of the upper section, the LiteRoc is lighter.
