Alpine Astronomical

The Alpine Astronomical Baader Hyperion 62mm-to-77mm DT Stepper-Ring is for use with the Hyperion 54mm-to-62mm DT-ring for attaching any of the fixed focal length or zoom Hyperion eyepieces directly to your larger DSLR camera lens for astrophotography. One side of the ring screws onto the front M77 lens filter threads and the other side attaches onto the 54mm-to-62mm DT-ring, acting as a step-up ring.
