Say goodbye to clunky counterweights and shafts—meet the HEM44 and HEM44EC, iOptron's game-changing mounts equipped with hybrid strain wave gear technology. These compact, lightweight mounts have the muscle to support a 44lb payload while tipping the scales at just 13.65lbs themselves. Thanks to iOptron's decades of expertise in precision mounts, that dream combo is now a reality.
When it comes to the tech inside, the HEM44 series knocks it out of the park. Its RA axis uses cutting-edge strain wave gears, paired with a backlash-free DEC worm/belt drive, delivering performance that's off the charts in terms of weight-to-payload efficiency. Sporting a black anodized, all-metal CNC machined body, this mount isn't just a looker—it's built to last.
But that's not all. The mount comes with nifty extras like an electronic friction brake and power-down memory. If the power cuts out, there’s no need to start over; the mount picks up right where it left off.
Control it your way: Windows PC users can opt for ASCOM/Commander, MacOS aficionados have third-party INDI driver options, and if you're more of a smartphone or tablet user, there's iOptron Commander Lite and apps like SkySafari. Raspberry Pi users, you're covered too, with INDI drivers.
For those craving even more precision, the HEM44EC version comes with a high-accuracy RA axis encoder, making it possible to capture images without even needing to guide.
