Alpine Astronomical Baader Hyperion 54mm-to-37mm DT-Ring

Easily connect your Hyperion or other Baader eyepiece to your camera's lens with the Alpine Astronomical Baader Hyperion 54mm-to-37mm DT-Ring for afocal and eyepiece projection astrophotography techniques. This version has 54mm threads to match the threads on the eyepiece, with 37mm threads to fit on your lens' filter thread, and requires the optional HEXT54 extension ring. Connecting the two components with this adapter makes a strong and secure fit, without tilt, for better performance. This kind of photography works best with telephoto lenses, rather than wide-angle lenses, and if the camera lens is smaller than the lens of the eyepiece. When using the Hyperion Zoom eyepiece the Hyperion Zoom M43/SP54 adapter is required; and when using the Morpheus eyepiece the Morpheus M43/SP54 adapter is required.
