The Alpine Astronomical M68 to T-2 Conversion Ring is a versatile set of adapters that allows you to mount a variety of gear and accessories onto focusers that have female M68 threads. The first adapter converts the M68 threads into 2" female threads to install filters or like-threaded accessories, and it comes with another adapter that takes the 2" female threads and converts them into standard male T2 photo threads, for compatibility with the entire T-2 Astro modular accessory system.
Alpine Astronomical Baader M68 to 2" UNFI Conversion Ring
The Alpine Astronomical Baader M68 to 2" UNFI Conversion Ring reduces M68 threads to 2" universal filter (UNFI) threads, which also fit most Schmidt-Cassegrain telescope (SCT) visual back threads. The front (telescope) side has male M68 threads and the back has standard 2" female eyepiece filter threads to mount a variety of gear, including filters and T-2 rings.
Alpine Astronomical Baader 2" Male to T-2 Male Adapter
Part of the T-2 Astro modular mounting system, the Alpine Astronomical Baader 2" Male to T-2 Male Adapter allows you to directly mount your DSLR onto Alpine's 2" Herschel Wedge, 2" Maxbright Diagonal, or other equipment that has standard 2" female mount threads. One side has male 2" threads to fit the diagonals and other gear, and the other has standard male T-2 threads that allow you to install camera-specific T-rings, extension tubes, or any of the other T-2 Astro accessories. Inner threads allow you to install standard 2" eyepiece filters.
