Alpine Astronomical Baader 2" Female SCT to Female M44ix1 Reducing Adapter

The Alpine Astronomical Baader 2" Female SCT to Female M44ix1 Reducing Adapter was originally designed to allow the use of their Hyperion Universal Zoom Mark IV eyepiece in any spotting scope equipped with M44ix1 male threads, and since it is just a simple reducer ring that fits standard 2" Schmidt-Cassegrain Telescope (SCT) threads, it can be used for a variety of applications beyond its initial intended application as either a general-purpose reducer or expander based on your needs.
