Stellarvue Field Flattener/Reducer for SV080A Access

Refractor telescopes naturally produce a curved image plane, which can cause stars at the edges of your frame to look elongated or out of focus. This accessory flattens that curvature, ensuring your stars remain sharp and pinpoint-accurate from the center all the way to the corners of your image.

This specific model is engineered with the optical characteristics of the SV080A Access in mind. While it may physically thread onto other telescopes, it is optimized for the focal length and design of the SV080A, so we recommend using it only with that specific model to ensure the best optical performance.

Yes, as a reducer, it shortens the effective focal length of your telescope. This provides a wider field of view and a faster focal ratio, which is particularly useful for astrophotography as it allows for shorter exposure times.

This flattener/reducer is designed to integrate into your imaging train, but you will still need a T-ring or specific camera adapter that matches your camera's mount to connect it to the back of the unit. Ensure you have the correct spacing requirements for your specific camera sensor to achieve optimal focus.

While field flatteners are primarily used to perfect images for astrophotography, they can also improve the view for visual observation by providing a flatter, more pleasing field of view. However, the primary benefit is most noticeable when capturing long-exposure images with a camera.
