XJ HM-17 Harmonic Equatorial Telescope Mount With Hand Controller, Lightweight High Load Astrophotography Mount, Precision Tracking for Telescopes, Compatible NINA, ASCAIR

⚙️ Lightweight Body with Exceptional Load Capacity: The mount weighs approximately 5.1 kg while delivering impressive rigidity and stability. It supports up to 13 kg without counterweights and up to 18 kg with counterweights, making it suitable for long focal length refractors, larger cameras, filter wheels, and complex imaging trains. Reinforced load-bearing areas help minimise micro-vibration and structural flex during imaging. 🎯 High-Precision Harmonic Drive for Accurate Tracking: Equipped with a premium harmonic reducer with a 400:1 reduction ratio, this mount achieves measured periodic error within ±10 arcseconds. The result is smooth tracking and reliable guiding performance, ideal for long-exposure astrophotography and deep-sky imaging. 🔄 Dual Equatorial & Alt-Azimuth Operation: Supports both equatorial and alt-azimuth modes with an adjustable altitude range from 0° to 90°. Easily switch between astrophotography and visual observation without changing the mount structure, offering excellent flexibility for different observing and imaging setups. 📡 Flexible Connectivity with Included Hand Controller: Powered by an open ONSTEP-based control system, the mount supports multiple wireless connection options. It can be operated via hand controller, computer, smartphone, and widely used astronomy software, allowing users to build flexible equipment combinations rather than being locked into a closed ecosystem. 🛡️ Advanced Safety, Memory & Control Features: Designed for reliability in real-world observing conditions, it includes an RA-axis electronic brake, power-loss memory, power interruption protection, mechanical home positioning, and fine adjustment mechanisms. These features enhance safety and stability during long imaging sessions, outdoor use, and unattended operation.
