The Baader Hyperion Digital T-Adapter permits direct coupling of any T-threaded camera or accessory to the M43 thread of the Hyperion Eyepieces as well as the Clickstop Zoom MARK III. These adapters give an external T-thread (M42x0.75) right at the eyelens of the Hyperions, which enables the Hyperions to be used with CCD and DSLR cameras for classic eyepiece projection photography. With this adapter, any of the Baader T-2 Extension Tubes can be used in-between the eyepiece and camera, to project and magnify the image as much as desired. The threaded direct-coupling makes this system extremely rigid and compact.
For the Clickstop Zoom MARK I and II, the Digital T-Adapter # HTA54/T2 attaches to the M54 thread of the Zoom (located under the rubber eyeguard).
