The EQ8-RH is a heavy-duty GoTo German equatorial mount rated for a 50 kg astrophotography payload excluding counterweights. This listing includes the pier 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 RH model adds a Renishaw high-resolution incremental encoder on the RA axis, specified at 11,840,000 counts per revolution or approximately 0.11 arcsecond. It reduces the influence of mechanical periodic error during tracking; it is not a second-axis encoder system.
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. The pier tripod weighs 29.4 kg and adjusts from 800 to 1100 mm. 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.
Exact R/RH and tripod distinction retained. Encoder values apply only to RH and are distinct from motor resolution and pointing accuracy. Manual weights exclude different components as labelled.
