The EQ8-R is a heavy-duty GoTo German equatorial mount rated for a 50 kg astrophotography payload excluding counterweights. This is the mount configuration without a tripod.
Drive and tracking
The 0.9° hybrid stepper motors use 256 microsteps and 435:1 worm drives. Maximum slewing speed is 3.7°/s. Sidereal, solar and lunar tracking, selectable autoguide rates and 200-segment permanent PEC are documented.
RA encoder
The standard EQ8-R does not include the Renishaw high-resolution RA encoder fitted to the EQ8-RH. Its motor-drive resolution must not be described as an encoder accuracy.
Installation and connections
The head weighs 25.8 kg; the counterweight rod weighs 2.6 kg and the documented counterweights are two 10 kg units. Provide a compatible tripod or permanent pier separately. Latitude adjustment covers 15–65° and azimuth adjustment ±10°. Internal auxiliary power/USB connections help route telescope cables.
Power and control
Use the manual’s 11–16 V DC, 55 W supply specification, with higher voltage preferred within that range. SynScan hand control and SynScan Pro provide GoTo operation with a 42,000+ object catalogue.
