M42 T-Ring for Nikon APS-C DSLR Cameras, Aluminum Adapter

**Key Product Features** **Dedicated APS-C Camera Compatibility** Specially designed for Nikon APS-C DSLR cameras only, this M42 T-ring adapter ensures accurate flange distance and proper optical alignment. Not suitable for Nikon full-frame or mirrorless camera bodies. **Seamless Telescope-to-Camera Connection** Converts your Nikon DSLR into a prime-focus imaging system by securely linking the camera body to telescopes, spotting scopes, and optical accessories—no camera lens required. **CNC-Machined All-Metal Structure** Constructed from solid aluminum alloy using precision CNC machining, then hard anodized for improved durability, scratch resistance, and long-term stability in outdoor observing environments. **Universal M42 × 0.75 Threading** Equipped with a standard M42 thread interface, allowing compatibility with most telescope T-adapters, extension tubes, and astrophotography components for a firm, vibration-reduced connection. **Manual Optical Focusing Control** Once installed, focusing is performed directly through the telescope’s focus system instead of camera autofocus, offering greater control for astrophotography, lunar imaging, and long-distance observation.
