The iOptron HEM44 is a revolutionary hybrid equatorial mount featuring strain wave drive technology on the RA axis combined with a backlash-free DEC worm/belt drive. Weighing just 13.65 pounds, it delivers an exceptional 44-pound payload capacity without requiring counterweights, making it ideal for portable astrophotography setups with telescopes up to 8-inch SCTs or 5-inch refractors. The mount includes the Go2Nova 8409 hand controller with a 212,000+ object database, Permanent Periodic Error Correction (PPEC) for accurate long-exposure tracking, and features a compact CNC-machined aluminum body with dual Vixen and Losmandy-D saddle compatibility. Its electronic friction brake and power-down memory ensure safe operation even during power loss, while built-in WiFi and USB connectivity allow control via computer, smartphone, or Raspberry Pi for flexible field and observatory deployment.
