Sky-Watcher EQ8-RH PRO Mount 20324
£6,220.00 VAT inc
The EQ8-RH PRO Mount is an extra heavy-duty, observatory class German equatorial mount, with an imaging payload capacity of up to 50kg. The EQ8-Rh is identical to the EQ8-R model except the EQ8-Rh features a high-end Renishaw encoder on the R.A. axis which allows astro-photography without an autoguider.

Quiet in operation, the EQ8-Rh is supplied with the Synscan™ Go-To handset and can automatically find and track over 42,900 celestial objects from its extensive computer database
INCLUDES HAND-CONTROLLER
Can be used with the optional 20293 pier tripod or be installed onto a static pier. Two 10kg counterweights and the Synscan computerised handset are supplied. The mount is also compatible with the optional Synscan™ Wi-Fi adaptor and Synscan™ Pro Apps which can control the mount wirelessly.
Permanent Periodic Error Correction
This mount is equipped with an index on its R.A. worm; thus, the motor controller can keep tracking the current position of the worm. After a proper PEC training routine, in which the training data is stored in the motor controller permanently, a user can start the periodic error correction (PEC) at any time to improve the tracking performance for short focal length astrophotography. A training process is not required in the next observing session (assuming that the polar alignment is always accurate); thus, this is a Permanent Period Error Correction (PPEC). A user can train the mount with manual guiding or auto-guiding. For detailed instructions,
Batch Exposures Function
Features include a SNAP port that can control a camera’s shutter release. SynScan hand control’s “Camera Control” function enables users to take batch exposures when doing astrophotography. Up to 8 groups of “Exposure-time & Frames” combinations can be set on the SynScan hand controller. For detailed information, refer to the SynScan hand control’s instruction manual.
Auto-Home Function
It is equipped with two home position sensors. Working with the SynScan hand controller, the mount can be placed to the same home position after turning on the power. For detailed information, refer to the SynScan hand control’s instruction manual.
The diagram below will be useful to those wanting to mount an EQ8 series head to an existing pier.
