About this product

Model:  skywatcher-EQ8-R-20323
Part Number:  20323

A solid workhorse at a bargain price! 

The NEW Sky-Watcher EQ8-R Pro is an evolutionary progression of the popular EQ8 Pro.

An extra heavy-duty, observatory class German Equatorial Mount with a payload capacity of up to 50kg.

Quiet in operation, the EQ8-R is supplied with the Synscan Go-To handset that can automatically find and track over 42,900 celestial objects from its extensive computer database.

Available either complete with pier tripod or as the mount head only, to install onto a static pier.

Two 10kg counterweights and the Synscan computerised handset are supplied with both options.

The mount is also compatible with the optional Synscan Wi-Fi adaptor and Synscan Pro Apps which can control the mount wirelessly.


Improvements over the previous EQ8 model include:

  • Cable management system for reduced tangling.
  • Improved Connectivity.
  • Improved installation position of motors for improved balance.
  • Improved clutch mechanism provides more holding strength.
  • Improved dovetail groove knob for added comfort and increased locking power.
  • Belt drive on the RA and DEC axes for quiet slewing (previously only the RA axes was belt driven).

Note: Freedom-Find encoders are not present on the EQ8-R


Permanent Periodic Error Correction

The EQ8 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

The EQ8 mount is equipped with a SNAP port which can control the shutter release of a camera. Working with the SynScan hand control’s “Camera Control” function, a user can 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

The EQ8 mount 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 head to an existing pier.

Eq8 r pro mount head
Tuesday, 2 November 2021  | 

The mount head came in a sturdy flight case and we'll packed. It is a very substantial mount and took my 12inch f4 Newtonian with breeze. Only had this a few weeks and only just got around to place in my observatory. Purchased a power supply from Flo as well and performed a home sync which was successful on first attempt. Easy to use with Eqmod too. I have no hesitation of recommending this mount if you're looking for something beefy to take heavy or multiple telescope's. Flo was excellent as usual, many thanks.

Rigid Mount
Friday, 11 September 2020  | 

Hello, Just received this mount head. Looks very rigid.
Powered on the mount and run the mount with maximum speed using controller (more features alike auto home). It sounds pleasing (wider belts drives).
More tests are pending, while observations, but I think it is going to be wonderful with it.
