iOptron HEM27 Mounting
The iOptron HEM27 brings top performance in a compact and portable design. Thanks to the advanced Harmonic Drive Technology moves the mount extremely smoothly and precisely - without heavy counterweights. That means less lifting, faster setup and more time to observe or photograph.
Powerful but light
The HEM27 weighs only 3.7 kg, but can handle up to 13.5 kg carry. Ideal for those who want to travel with a heavier telescope without dragging ballast. The high carrying capacity and low mass make this an excellent choice for mobile astrophotographers.
Smart technology for effortless use
With the built-in Go2Nova 8408 control and hand controller you easily navigate through a database of 212,000 sky objects. The mount tracks accurately - even without autoguiding - so your images remain clear and stable.
No cable clutter
All cables run internally. That keeps your setup tidy and prevents cables from getting tangled during tracking.
Safe and reliable
Does the power go out? The HEM27 automatically stops and maintains its position. As soon as the power is back, you can continue immediately without re-aligning.
Smart details that make a difference
With features such as PEC correction (for error-free tracking), Easy Polar Alignment, built-in WiFi, and a dual Vixen & Losmandy saddle, this mount offers everything you need for accurate, trouble-free sessions.
Built for peak performance
The CNC-machined aluminum construction feels solid and offers the precision you expect from iOptron. Perfect for observers and astrophotographers who want a reliable, lightweight but powerful mount.
