The iOptron CEM120<\/strong> is built for serious astrophotographers and observers who want maximum stability and accuracy. This mount takes your sessions to the next level with a carrying capacity of 52 kg<\/strong>, an innovative centrally balanced design and advanced technology for error-free tracking.<\/p>\n\n\n\n

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

Cleverly designed for perfect balance<\/strong>
The secret of the CEM120 lies in the centrally balanced design<\/strong>. The weight of your telescope rests directly over the center of the tripod or column, distributing the load evenly. The result? An exceptionally stable base that moves smoothly and vibration-free even in heavy setups.<\/p>\n\n\n\n

Heavy loads, light operation<\/strong>
Despite its huge payload capacity of 52 kg, the mount itself weighs only 26 kg. The precise gear clutches<\/strong> make it easy to lock or unlock, even with gloves on. This means quick setup, smooth movement and less time wasted adjusting.<\/p>\n\n\n\n

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

Designed for razor-sharp astrophotography<\/strong>
The stepper motors with 0.07 arc second accuracy<\/strong> ensure that your objects stay exactly in focus - ideal for long exposures and deep-sky photography. With permanent periodic error correction (PPEC)<\/strong> or real-time PEC (on EC models) tracking remains stable and error-free, recording after recording.<\/p>\n\n\n\n

Operate your way<\/strong>
The CEM120 offers you ultimate freedom: control it via hand controller, Wi-Fi, LAN or PC (ASCOM)<\/strong>. The built-in Go2Nova 8407 V2 system<\/strong> with more than 200,000 objects helps you find any target in the sky at lightning speed. And thanks to the built-in GPS<\/strong> and illuminated interface you work effortlessly even in total darkness.<\/p>\n\n\n\n

Smart cable management for peace of mind in your setup<\/strong>
The integrated cable management system<\/strong> prevents entanglement and protects against breakage. All connections are right where you need them, keeping your setup tight and secure - important during nighttime sessions where every move counts.<\/p>\n\n\n\n

Three versions, one performance standard<\/strong>
The CEM120 is available in three variants: the CEM120<\/strong>, CEM120EC<\/strong> (with encoder on RA axis) and CEM120EC2<\/strong> (encoders on both axes). The EC models offer nearly error-free tracking even at the longest exposures.<\/p>\n\n\n\n

Whether you're shooting from your backyard or working with a full-fledged observatory setup - the CEM120 gives you the control, precision and stability you need.<\/p>\n\n\n\n
