HEM27 EQ SWG Hybrid Mount with iPolar
Now Available at Modern Telescopes – Authorized Distributor
Introducing the HEM27 EQ SWG Hybrid Mount with iPolar, a next-generation equatorial mount engineered for astronomers who demand maximum payload capacity in a remarkably compact, lightweight form. Designed by iOptron, the HEM27 series blends advanced strain wave (harmonic) drive technology with a backlash-free DEC worm/belt system, delivering an observing and imaging experience that redefines portability and precision.
Tiny Titan. Serious Performance.
Imagine a mount head weighing just 8.15 lbs (3.7 kg) that effortlessly handles 29.74 lbs (13.5 kg) of payload—without a counterweight. That’s the power of iOptron’s decades-long expertise distilled into a compact hybrid design built for both visual observers and astrophotographers. The HEM27’s all-metal, CNC-machined, black anodized body is rugged, elegant, and made to perform flawlessly for years.
Hybrid Drive Excellence
The HEM27 utilizes a StrainWave 17 gear system in RA combined with a precision backlash-free DEC worm/belt drive, achieving an outstanding payload-to-weight ratio of 3.65. An electronic friction brake safeguards your equipment by instantly stopping movement during both planned and unplanned power interruptions—peace of mind you can rely on in the field.
iPolar Inside – Fast, Accurate Alignment
Integrated iPolar electronic polar scope technology makes polar alignment fast, accurate, and hassle-free, even under light-polluted skies—perfect for portable astrophotography setups.
