Sky-Watcher EQ8-R Series Polar Scope
The Sky-Watcher EQ8-R Series Polar Scope (S30615) is the dedicated alignment accessory for the heavyweight EQ8-R and EQ8-Rh mounts. This kit, which includes 1 mounting bracket and 1 polar scope, features an etched reticle with distinct markings for both hemispheres and is not compatible with the EQ6-R or HEQ5 series.
Purpose-Built for the EQ8-R and EQ8-Rh Mounts
This polar scope is made exclusively for the Sky-Watcher EQ8-R and EQ8-Rh mounts. The small polar scope slides into the included mounting bracket, which attaches directly to the mount.
It is not compatible with the EQ6-R, HEQ5 or any other Sky-Watcher mount, so it is intended only for owners of EQ8-R series mounts.
Dual-Hemisphere Reticle and Multi-Coated Optics
The scope's etched reticle is designed for use in both hemispheres. It features alignment circles for Polaris (Northern Hemisphere) and Sigma Octantis (Southern Hemisphere), with hour-angle calibration.
-
Multi-Coated Optics: The polar scope uses a multi-coated optical design.
-
User Adjustments: A built-in diopter allows you to focus the reticle sharply to match your eyesight. For precise calibration, the reticle position can be aligned to the mount's axis of rotation using adjustment screws.

Is the Sky-Watcher S30615 Polar Scope compatible with an EQ6-R Pro mount?
No. The S30615 polar scope is designed exclusively for the Sky-Watcher EQ8-R and EQ8-Rh mounts. It is not compatible with the EQ6-R, HEQ5 or any other Sky-Watcher mount.
How do I align the reticle in the EQ8-R Polar Scope?
The polar scope has adjustment screws for reticle calibration, used to align the reticle with the mount's axis of rotation. Refer to your EQ8-R series mount documentation for the full procedure.
Can I use the Sky-Watcher EQ8-R Polar Scope in Australia or other Southern Hemisphere locations?
Yes. The polar scope's etched reticle includes an alignment circle for Sigma Octantis in the Southern Hemisphere, as well as one for Polaris in the Northern Hemisphere.
Does the EQ8-R Polar Scope include the bracket needed to attach it to the mount?
Yes, the package includes both the polar scope itself and the mounting bracket that attaches directly to the Sky-Watcher EQ8-R and EQ8-Rh mounts. The polar scope slides into the bracket.
Why is the S30615 polar scope needed for accurate alignment with an EQ8-R mount for astrophotography?
For long-exposure astrophotography, accurate polar alignment helps keep stars sharp and reduces the corrections your guiding has to make. Retailers state that with a properly adjusted polar scope you can achieve alignment accuracy within a few arcminutes.
How do I focus the Sky-Watcher EQ8-R polar scope for my eyesight?
The polar scope has a built-in focus (diopter) adjustment. Adjust it while looking through the scope until the etched reticle pattern appears sharp for your eyesight.
