Hyperion Zoom Adapter M43/SP54. With this adapter, Hyperion DT rings can be connected to the Hyperion Zoom Eyepiece Mark III, allowing it to be coupled with camera lenses, for example. Since the coupling is done through the filter thread of the lenses, at least one DT ring for the corresponding thread is additionally required. The DT rings SP54/M28 and SP54/M37 also require the extension ring 2958090. The adapter is intended only for the Zoom Mark III.
