  • AG Wynne corrector to fit SBIG using 41mm BFD with +-4mm adj

    Designed by Orion Optics UK for their fast AG-series astrographs, this AG Wynne corrector delivers a flat, coma-free field for SBIG cameras by establishing a precise 41mm back focus distance, which can be fine-tuned with a ±4mm adjustment range to achieve critical sensor placement.

    Coma Correction for Orion Optics AG Astrographs

    Fast Newtonian astrographs, like the Orion Optics UK AG series, naturally produce off-axis coma, an aberration that elongates stars into comet-like shapes away from the center of the field. This Wynne corrector is optically matched to the AG system to cancel this aberration, ensuring stars remain sharp, round pinpoints across the entire imaging sensor.

    Each corrector is manufactured to the same high standards as Orion Optics UK's primary mirrors. This ensures that the correction does not introduce other aberrations and preserves the high-resolution performance of the main optical system, which is essential for "elite astrophotography."

    Precision 41mm Back Focus for SBIG Cameras

    A corrector's performance is critically dependent on the distance between its rear lens element and the camera's sensor. This model is engineered with a specific 41mm back focus distance (BFD) to perfectly match the mechanical requirements of SBIG camera bodies, removing guesswork from the setup process.

    The integrated ±4mm adjustment range provides the necessary flexibility to accommodate the added path length of accessories like filter wheels or off-axis guiders. This allows you to dial in the exact spacing required for perfect correction across the field, ensuring your final images are free of optical errors.

  • What is the primary function of this Orion Optics UK AG Wynne corrector?

    The primary function of this corrector is to eliminate coma, an optical aberration inherent in fast Newtonian telescopes like the Orion Optics AG series. It ensures that stars are rendered as sharp points across the entire field of view, which is critical for high-resolution astrophotography.

    Why is this Wynne corrector specific to SBIG cameras?

    This corrector is mechanically and optically designed to provide a nominal back focus distance of 41mm. This specific distance matches the flange-to-sensor distance of many SBIG cameras, ensuring proper spacing for optimal optical correction without requiring a complex set of adapters.

    How do I use the ±4mm adjustment on this AG Wynne corrector?

    The ±4mm adjustment is used for fine-tuning the back focus. If you add a component like a filter wheel or off-axis guider into your imaging train, it increases the optical path length. The adjustment allows you to compensate for this added distance to restore the perfect 41mm spacing between the corrector and the sensor.

    Will this Orion Optics UK corrector work with a non-SBIG camera?

    While it might be physically possible to attach another camera, it is not recommended. The corrector's optical performance is optimized for the 41mm back focus. A camera with a different back focus (e.g., 55mm for many CMOS/DSLR cameras) would require additional, precise adapters and may not achieve the same level of correction.

    I have an Orion Optics AG12 and an SBIG camera with a filter wheel. Is this the right corrector?

    Yes, this corrector is an ideal match. The Orion Optics AG12 is precisely the type of instrument this corrector is designed for. The ±4mm adjustment range is specifically included to help you achieve the correct 41mm spacing after accounting for the thickness of your filter wheel.

    Is this corrector suitable for visual use with an eyepiece?

    No, this is a dedicated photographic corrector. It is not designed to work with eyepieces and will not reach focus for visual observation. Its purpose is solely to create a corrected, flat field for an imaging sensor placed at a specific back focus distance.
