E-mount adapter for 1.25-inch telescope eyepiece

An adapter to attach Sony e-mount cameras to a telescope with a 1.25-inch eyepiece receptacle. Consists of 4 parts which assemble without any additional fasteners or adhesive. Crucially, the adapter features a complete e-mount interface which latches to the camera body and has a long enough tube so that the camera sensor can be positioned at the focal length of the Celestron travel scope without exhausting the focuser's range.
