iOptron HEM44 EC Mount iPolar: hybrid precision mount with RA encoder<\/strong><\/h2>\n\n\n\n

The iOptron HEM44 is a hybrid equatorial mount: strain wave drive on the right ascension axis, backlash-free worm and belt drive on the declination axis. Without a counterweight, it carries 20 kg (44 lbs) in a head that remains light enough for mobile use.<\/p>\n\n\n\n

The EC version measures the right-ascension axis using a high-resolution encoder and corrects the periodic error in real time. For short and medium brand point distances, you can take photos without autoguiding, silently, and unattended.<\/p>\n\n\n\n

The built-in iPolar also makes polar alignment exact: together the shortest route to sharp stars.<\/p>\n\n\n\n

Real-time error correction on the RA axis<\/strong><\/h4>\n\n\n\n

The encoder continuously adjusts without PEC training or a guiding camera. For long brand point distances, the ST-4 port remains available.<\/p>\n\n\n\n

When combined with precise iPolar alignment, the usable unattended exposure time increases significantly.<\/p>\n\n\n\n

Hybrid drive without counterweight<\/strong><\/h4>\n\n\n\n

The combination of strain wave on RA and worm\/belt on declination provides the load capacity of a harmonic drive with the refined tracking behavior of a traditional drive. A counterweight is unnecessary in most setups.<\/p>\n\n\n\n

The electronic friction brake safely stops the mount during a power failure, and the power-down memory preserves position and alignment.<\/p>\n\n\n\n

Complete control<\/strong><\/h4>\n\n\n\n

The Go2Nova 8409 hand controller contains over 200,000 objects; Wi-Fi is routed through the hand controller, and computer control is possible via ASCOM, INDI, or iOptron Commander. Autoguiding via the ST-4 port and PEC correction are built-in.<\/p>\n\n\n\n

The internal cable management and the dual Vixen\/Losmandy-D saddle keep the photo setup tidy; the built-in zero-position finder automatically finds the starting position.<\/p>\n\n\n\n
