iOptron HEM27 Mount - Compact Power with Harmonic Drive Technology<\/strong><\/p>\n\n\n\n

The iOptron HEM27<\/strong> is built for observers who want maximum performance in a lightweight and portable design. Thanks to the advanced Harmonic Drive technology<\/strong> you enjoy smooth, accurate tracking without the hassle of counterweights. Ideal if you are often out and about or like to travel with your telescope.<\/p>\n\n\n\n

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

Light but powerful<\/strong>
The HEM27 weighs only 3.7 kg<\/strong>, but can still reach 13.5 kg<\/strong> carry. That means you get a sturdy setup without heavy ballast. Perfect for astrophotographers and visual observers who want mobility without sacrificing stability.<\/p>\n\n\n\n

Smart and user-friendly<\/strong>
The built-in iPolar pole finder<\/strong> makes alignment easy and fast, even in low light. Internal cable routing keeps your setup tidy and prevents cables from getting tangled during tracking or slewing.<\/p>\n\n\n\n

Reliable GoTo Accuracy<\/strong>
With the Go2Nova 8409 controller<\/strong> Get access to more than 212,000 sky objects<\/strong>. Operation is intuitive, allowing you to find stars, nebulae or planets in seconds. The automatic stop function<\/strong> on power failure protects your telescope and maintains alignment.<\/p>\n\n\n\n

Exceptional tracking even without guiding<\/strong>
Thanks to Periodic Error Correction (PEC).<\/strong> tracking remains stable and smooth. Your images remain sharp even during long exposures. The Harmonic Drive motors<\/strong> work silently, without backlash, meaning your object stays exactly where you want it.<\/p>\n\n\n\n

Double saddle for maximum flexibility<\/strong>
Whether you have a Vixen<\/strong> or Losmandy<\/strong> mounting plate used, the HEM27 is directly compatible with both. This makes it easy to change optical tubes without additional adapters.<\/p>\n\n\n\n

Ready for modern astrophotography<\/strong>
With USB and ST4 ports<\/strong>, WiFi connectivity<\/strong>, and autoguiding support<\/strong> the HEM27 is immediately ready for use with popular software and cameras.<\/p>\n\n\n\n
