A Wider, Faster Field of View for ED80Sf Owners Using Sony α Cameras

This focal reducer is made specifically for the ED80Sf refractor paired with a Sony α camera. It shortens the focal length from 600mm to ~510mm (f/6.4), giving you a wider field of view and faster exposures — ideal for shooting large nebulae, star fields, and Milky Way regions.

The Sony α mount adapter is included, so no additional parts are needed to connect your camera directly.

Note: for imaging only — not compatible with eyepieces for visual use. Compatible with the ED80Sf only.

Who This Is For

  • ED80Sf owners using a Sony α camera for deep-sky astrophotography
