AD-58 DSLR Adapter
Mount any 1.25″ filter cell (including Star Analyser or Rainbow Optics gratings) to DSLR filter threads.
This filter fits the standard 58 mm lens cap threads like those found on Canon cameras.
If your camera's filter threads are not 58 mm, you will need some step up or step down Adapter Rings (link).
