The Celestron Equatorial Wedge is designed for NexStar 6SE, NexStar 8SE and compatible NexStar Evolution telescopes when you want to move beyond short-exposure imaging and start taking longer deep-sky photographs.
In its normal alt-azimuth configuration, your telescope can track an object across the sky, but the field of view gradually rotates during longer exposures. That field rotation limits how long you can expose before stars begin to trail or rotate around the image.
The wedge tilts the mount so it can be polar aligned with the Earth's rotational axis. Once correctly aligned, the telescope tracks the sky in an equatorial configuration, eliminating field rotation and allowing substantially longer exposures.
That opens the door to capturing more detail in nebulae, galaxies and other faint deep-sky objects, as well as progressing towards guided astrophotography.
Celestron has designed the wedge specifically around the NexStar SE and Evolution single-fork mounts, with fine latitude and azimuth adjustments to help achieve accurate polar alignment. Captive hardware and tool-free adjustment make setup straightforward while keeping the mount securely supported.
For NexStar SE and Evolution owners ready to take their astrophotography further, the EQ Wedge is the key upgrade that allows the existing GoTo mount to work in a true equatorial configuration.
Why Choose the Celestron EQ Wedge?
-
Enables longer-exposure astrophotography — move beyond the limitations of standard alt-azimuth tracking.
-
Eliminates field rotation — essential when exposure times become long enough for rotation to affect star shapes.
-
Converts your existing mount to equatorial operation — no need to replace the complete NexStar SE or Evolution mount.
-
Improves deep-sky imaging capability — capture more detail in nebulae, galaxies and other faint targets.
-
Supports guided imaging — provides the equatorial tracking configuration required when progressing to autoguiding.
-
Precision latitude and azimuth adjustment — makes accurate polar alignment easier.
-
Purpose-built for Celestron single-fork mounts — designed for secure integration with compatible NexStar SE and Evolution telescopes.
-
0°–70° latitude adjustment range — suitable for observing locations throughout New Zealand.
Do I Need a Wedge?
If you primarily use your NexStar for visual astronomy, planetary imaging or short-exposure photography, the normal alt-azimuth setup remains simple and effective.
The wedge becomes valuable when you want to take longer exposures of faint deep-sky objects. By polar aligning the mount and eliminating field rotation, it allows your existing telescope to progress into more advanced astrophotography without replacing the mount.
FAQ's
Which Celestron telescopes is this wedge compatible with?
It is designed for the NexStar 6SE, NexStar 8SE, NexStar Evolution 6, Evolution 8 and Evolution 8HD single-fork mounts.
It is not compatible with the NexStar Evolution 9.25, which requires Celestron's larger HD Pro Wedge.
What does an equatorial wedge actually do?
It tilts the telescope mount so its tracking axis can be aligned with the Earth's rotational axis. This allows the telescope to follow the sky without the field rotation that occurs during longer exposures with a standard alt-azimuth mount.
Will the wedge improve normal visual observing?
It is primarily an astrophotography accessory. For normal visual observing, the standard alt-azimuth configuration is generally simpler and works extremely well.
Do I still use the telescope's GoTo and tracking system?
Yes. The wedge changes the geometry of the mount rather than replacing its electronics. Your compatible NexStar SE or Evolution mount continues to provide computerised pointing and motorised tracking, but in an equatorial configuration once correctly set up and aligned.
