iOptron CEM40-EC - Compact Power with Professional Accuracy<\/strong><\/h2>\n\n\n\n

The iOptron CEM40-EC<\/strong> is made for those who want mobility without sacrificing precision. At only 8.2 kg, this mount is surprisingly light, yet strong enough to carry up to 18 kg of optics and accessories. Ideal for traveling observers or as a permanent setup in your garden observatory.<\/p>\n\n\n\n

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

Smart, precise and easy to use<\/strong><\/h3>\n\n\n\n

The built-in\u00a0iPolar electronic polar finder<\/strong>\u00a0makes alignment easy - even when the North Star is not visible. Just plug in your laptop or PC, and the software does the rest. The\u00a0internal cable system<\/strong>\u00a0keeps everything neat and prevents cable breakage. The large clamps, even with gloves on, allow you to easily unlock the axles. <\/p>\n\n\n\n

The\u00a0Universal Self-Centering Saddle<\/strong>\u00a0Works with both Losmandy and Vixen swallowtails, so you can switch between telescopes without any problems.<\/p>\n\n\n\n

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

Quiet power and high precision<\/strong><\/h3>\n\n\n\n

The quiet stepper motors track smoothly and accurately without disturbing noise - perfect for balcony observations.
The high-resolution encoders<\/strong> on both axes provide tracking accuracy of less than 0.25 arc second<\/strong>. Thus, in astrophotography you no longer need to use guiding - the mount corrects itself in real time.<\/p>\n\n\n\n

With the Go2Nova 8407+ operating system<\/strong> quickly navigate to more than 359,000 objects. The backlit screen prevents condensation and the built-in GPS<\/strong> Automatically sets time, date and location.<\/p>\n\n\n\n

Strong, stable and portable<\/strong><\/h3>\n\n\n\n

The LiteRoc tripod<\/strong> is sturdy, lightweight and made for mobile use. The thick 45 and 38 mm steel legs provide additional stability, while the new clamping levers allow for quick adjustment.<\/p>\n\n\n\n

Whether you are photographing or just observing - the iOptron CEM40-EC<\/strong> Delivers reliable performance in a lightweight design.<\/p>\n\n\n\n
