iOptron CEM40 Mount with Tripod: GoTo Mount with Tripod
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 comes with a matching tripod, making it a ready-to-use setup for visual observation and astrophotography.
The silent stepper motors and internal cable management make the mount pleasant for daily use.
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.
