Sky-Watcher Reducer/Flattener for Esprit

No, this specific reducer/flattener is optically engineered exclusively for the Sky-Watcher Esprit 120. Using it with other telescope models will likely result in poor image quality and an inability to reach proper focus.

By shortening your focal ratio, this unit allows your sensor to capture more light in less time. This means you can achieve the same signal-to-noise ratio in significantly shorter sub-exposures, which helps reduce tracking errors and maximizes your time under clear skies.

Yes, this unit provides a 34mm fully illuminated field, making it compatible with both full-frame and APS-C sensors. It is designed to maintain edge-to-edge sharpness across these sensor sizes.

The unit offers a native back-focus of 95mm, which provides plenty of room for various imaging trains. If you need to reach the standard 55mm distance for many common DSLR or mirrorless setups, you can simply use the included spacer and ring to adjust it accordingly.

Not at all. The reducer features a built-in 2-inch filter cell, allowing you to easily thread in your preferred light pollution or narrowband filters directly into the imaging train without needing extra adapters.
