iOptron CEM40 Mounting GoTo LiteRoc

iOptron CEM40 Mount GoTo LiteRoc: center-balanced mount for serious astrophotography

The iOptron CEM40 is a centrally-balanced equatorial GoTo mount with a payload capacity of 18 kg (40 lbs) excluding counterweight, at a head weight of only 7.2 kg (15.8 lbs). The weight of the mount and telescope rests directly above the center of the tripod, giving a remarkably quiet and stable setup.

This version sits on the LiteRoc stainless steel tripod, making it a complete setup for refractors up to approximately 130 mm, compact astrographs, and Newtonians for astrophotography.

With head and tripod, the kit remains light enough to regularly take along to dark locations.

GoTo, GPS, and heated handgrips

The Go2Nova 8407+ hand controller contains a database of over 200,000 objects and has a built-in display heater, so the screen remains readable even in freezing temperatures. The 32-channel GPS in the mount automatically sets the time and position.

Computer control is via USB. Wireless control with SkySafari or ASCOM is possible with the optional iStarFi WiFi module. An ST-4 port is ready for autoguiding.

Accurate and quiet mechanism

Low-consumption stepper motors control both axes. The periodic error remains within plus or minus 7 arcseconds and can be further reduced with recording PPEC.

The dual saddle accommodates Vixen and Losmandy rails, the large geared clutch levers also work with gloves on, and internal cable management keeps the setup tidy.

Built-in iPolar

The iPolar electronic polar finder is standard in the polar axis. You align it on your laptop screen, even without a clear view of Polaris, with a precision that an optical finder cannot achieve.
