Our 2-part adapter is designed for photovisual use. Visually with an optimal distance of 105mm when using standard eyepieces. The clamping mechanism is the APM-Deluxe brass centering clamp. The upper part is 55mm long and can be unscrewed, so that a T2 thread appears and cameras with 55mm required total back focus (DSLR + T2 ring) can be used.

The T2 adapter has the right screw-in thread for our Düring Barlow lens.
