Sky-Watcher EQ8-R Mount (Without Tripod) - German Equatorial Mount, 50 kg Payload, SynScan Go-To

The Sky-Watcher EQ8-R is a professional-grade German Equatorial Mount designed for serious astrophotographers and visual observers. With a massive 50 kg payload capacity and precision stepper motor drives, it delivers exceptional stability and tracking accuracy for large telescopes and heavy imaging setups. The mount head is constructed from CNC-machined aluminum and steel, ensuring durability and vibration dampening. The built-in SynScan Go-To system with a database of over 42,900 objects makes locating celestial targets effortless. This version is supplied without a tripod, allowing you to pair it with your preferred pier or heavy-duty tripod.

Advantages

The EQ8-R offers a high payload-to-weight ratio, with the mount head weighing only 28.5 kg while supporting up to 50 kg of equipment. The belt-driven stepper motors provide smooth, quiet slewing and excellent periodic error correction with Permanent PEC (PPEC). The built-in GPS and multiple connectivity options (USB-B, RS-232, hand controller port) make it easy to integrate with observatory control systems. The Losmandy D-plate saddle ensures compatibility with a wide range of telescopes.
