Esprit 80ED, 100ED, 120ED and 150ED Super APO refractors have a doublet field flattener to get a flat field and minimize aberration and distortion. Their wide 48mm opener ensures a larger and clearer aperture and also extremely minimized halation. Connect the triplet and doublet field flattener with a high precision thin thread to keep the optical axis perpendicular to the image.

Main Features:

- Premium optical materials

- Short focal length and full frame corrected focal plane

- Excellent field flatness

- Precision linear power focuser is standard

- Metallic high-transmission lens coatings

- Light-baffled optical systems

- Telescope tube attachment hardware

- Full-frame Corrected Focal Plane

- Zero detectable Colour Fringing even on Bright Objects

- Knife-edge Baffled Optical System

All Sky-Watcher Esprit refractors come with a 9 x 50 right angle finderscope, 2-inch Star diagonal, 2-element field flattener, camera adapter, D-style dovetail and padded case. Everything you need to get out under the stars.

The EQ8 High Precision EQ mount is pier tripod - based. It comes with SynScan hand controller, 2x10kg counterweights and GPS, with a payload of 50kg. The patented Freedom Find (dual-encoder) technolgy allows the telescope to be moved manually whenever the user wishes - but with no need for re-alignment!


  • Freedom FindTM Function
The EQ8 mount is equipped with auxiliary encoders on both the R.A. axis and Dec. axis. Therefore, the mount can keep tracking its current position even when a user unlocks the clutches and rotates the mount in R.A. axis and Dec. axis manually. With this feature, a user can manually operate the mount anytime without worrying about losing the mount’s alignment status. When the user wants to operate the mount with the SynScan hand control again, no alignment is required and all that is needed to be done is to re-lock the clutches.
This feature can be enabled or disabled on the SynScan hand controller.
  • 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.
