The iOptron CEM40<\/strong> offers a unique balance of portability, power and precision. Weighing only 8.2 kg<\/strong> Can this mount accommodate telescopes up to 18 kg<\/strong> carry. That means: solid, reliable tracking without having to lift a heavy setup.<\/p>\n\n\n\n

\"iOptron<\/figure>\n\n\n\n

Smart and user-friendly design<\/strong><\/h3>\n\n\n\n

Thanks to the Center-Balanced Equatorial Mount (CEM).<\/strong>-design keeps the center of gravity perfectly centered. This gives you more stability and less vibration - exactly what you need for sharp, stable images.<\/p>\n\n\n\n

The built-in iPolar electronic polar finder<\/strong> makes alignment easy, even when the North Star is not visible. Plug in your laptop, follow the software, and you'll be ready to observe in minutes.<\/p>\n\n\n\n

Easy to operate even in the dark<\/strong><\/h3>\n\n\n\n

The Go2Nova 8407+ hand controller<\/strong> has a large, backlit screen with built-in heating against condensation. The database contains more than 359,000 objects<\/strong>, allowing you to find any desired celestial body at the touch of a button. The integrated 32-channel GPS<\/strong> saves time - no more manual entry of date, time or location.<\/p>\n\n\n\n

Quiet, precise and reliable<\/strong><\/h3>\n\n\n\n

The stepper motors<\/strong> operate virtually silently and consume little power - ideal for balcony observations or mobile setups. The internal cable system prevents loose wires and damage during use.<\/p>\n\n\n\n

The Universal Self-Centering Saddle<\/strong> fits both Vixen<\/strong>- as Losmandy<\/strong>-rails. This makes it easy to switch between different telescopes without worrying about alignment.<\/p>\n\n\n\n

Ready for astrophotography<\/strong><\/h3>\n\n\n\n

Want to raise the bar even higher? The CEM40-EC<\/strong>-variant has high-resolution encoders<\/strong> on both axes. These correct the periodic error in real time and provide an accuracy of less than 0.25 arc seconds<\/strong>. That means: super-smooth tracking - without autoguiding.<\/p>\n\n\n\n

Light, stable and mobile<\/strong><\/h3>\n\n\n\n

The mount comes with the LiteRoc stainless steel tripod<\/strong>, specially designed for maximum stability with minimal weight. The thicker legs and sturdy clamps keep your setup stable even during long exposures.<\/p>\n\n\n\n

The iOptron CEM40<\/strong> is built for astrophotographers and observers who want serious performance in a portable, modern form.<\/p>\n\n\n\n
