I need a lockable T-2 extension, total length about 10 mm (for use with the Geoptik CCD-Canon connector). Can the 7.5 mm T-2 extension be combined with the #33 locking ring to achieve this? If not, is there another T-2 system item(s) for this? Thanks.

Passt hervorragend
Habe gleich drei Stück erworben, um damit die empfohlenen 65mm Abstand zwischen Kamerasensor und T2-Anschluss vom BAADER SUNDANCER II zu erreichen, da das 15mm Zwischenstück leider nicht lagernd war/ist.
  • Sitzt, passt, funktioniert.
