Because these mounts are observatory class we are offering them in two configurations. For the field imager both mounts include the mount head, two 22 pound weights and a heavy-duty portable pier. For those installing into an observatory, you can purchase the mount head and weights without the tripod.
EQ8-R & Rh features:
High Payload capacity
The EQ8-R series features a massive 110 pound payload capacity.
Built-In cable management
Cable management is an important part of the imaging experience. To aid in this the EQ8-R series features three collections of cable hubs built in below the mounting saddle. The mounts feature four USB 3.0 ports, three 2.1mm power ports and three serial cable ports. Plug all your imaging accessories into these ports and eliminate cable drag and snags from the equation. You can then plug one USB 3.0 cable and one power cable into the back of the RA housing to have a simple and clean set up free of hanging cables.
The EQ8-R and Rh series feature homing sensors on both the RA and Dec. axis. Homing sensors aid in alignment accuracy of the first star as the mount starts at an exact preset position every time. For remote imaging these sensors allow the mount to maintain alignment in case of power outages. Simply home the mount and the mount can pick up from it's previous alignment.
Both the RA and Dec. motor assemblies drive the mount using ultra-smooth belt drives. This reduces the amount of gearing needed which in turn reduces backlash in the system and periodic error overall.
Like other Sky-Watcher mounts the EQ8-R series features a built-in SNAP port. This allows you to plug in your DSLR or mirrorless camera of choice and control the shutter through the hand controller. The camera will require the correct optional cable to make this connection. See our offering of SNAP cables at skywatcherusa.com.
PC Direct Connect
A built-in USB-B port is situated on the mount to allow a direct connection to your computer, no hand controller needed! Plug it in, power on the Sky-Watcher SynScan Pro app for Windows and take control of your mount.
Improved Motor Placement
Growing from the original EQ8, the EQ8-R series features improved motor positioning. This aids in balance of the mount, eliminating uneven side balance inherent in the previous design.
EQ8-Rh On-Axis Encoder (Only found on the Rh model)
Additionally, EQ8-Rh model also features an on-axis RA encoder. The Renishaw 11.8-million tick incremental encoder is mounted directly to the RA shaft of the mount. This virtually nearly eliminates Periodic Error during tracking and allows for extremely precise tracking and guiding for the most demanding astrophotographers.
