Baader Hyperion DT Ring HDT72/82 (M72 to M82, for use with HDT54/62 + HDT62/72) # 2958082. Other rings in this series referenced below are sold separately.
Baader Hyperion Digital T-Rings enable you to couple practically any digital camera, camcorder, or CCD Camera directly to the 54mm thread of the Baader Hyperion fixed focal length eyepieces and Mark II Clickstop Zoom (these rings are not for use with the newer Hyperion Mark III or Mark IV zoom eyepiece).
Hyperions make the ideal projection eyepiece for afocal projection imaging, delivering a very sharp projected image without any vignetting. The direct threaded coupling permitted by the Digital T-rings results in the most accurate and rigid attachment possible even with large and heavy cameras and video cameras. This system also allows the cameras lens to be located immediately above the large eyelens for eliminating the vignetting common in other systems (afocal projection).
- For attaching cameras with 28mm or 37mm filter threads, you will need the appropriate HDT ring as well as a 54mm extension ring (sold separately).
- For attaching cameras with filter threads from 46mm to 62mm, a single HDT ring will suffice.
- For attaching cameras with filter threads from 67mm to 77mm, you will need two step-up rings; the HDT54/62 ring + the appropriate HDT62/xx ring.
- For attaching cameras with an 82mm filter thread, you will need three step-up rings; the HDT54/62 ring + the HDT62/72 ring + the HDT72/82 ring.
