Alpine Astronomical Baader Hyperion 72-to-82mm DT Stepper Ring

The Alpine Astronomical Baader Hyperion 72-to-82mm DT Stepper Ring is used with the Hyperion 54-to-62mm and 62-to-72mm DT-rings for attaching any of the fixed focal length or zoom Hyperion eyepieces directly to your large DSLR camera lens for various eyepiece astrophotography techniques. Each successive ring increases the thread diameter while providing a strong connection to ensure optical alignment.
