Lumicon 2" Prime Focus Direct Camera Adapter with Canon EF Mount

The Lumicon 2" Prime Focus Direct Camera Adapter allows your Canon EF camera to be inserted directly into any 2" telescope focuser for astrophotography, without an eyepiece in the optical path. This technique, known as prime focus, makes your telescope the camera's lens. Instead of the more common T-threads that this type of adapter is usually outfitted with, this adapter has a Canon EF bayonet mount that eliminates the need for an additional T-ring—which makes a more solid and secure connection without the possibility of the ring backing off the adapter.
