The Baader # 1508020 inverter is a simple SCT externally threaded ring, which can be used to convert internal SCT threads to external SCT threads (gender changer). This adapter has a male SCT thread (2" x 24 TPI specification) all along its outside. Total adapter / SCT male thread length = 11.9mm (0.47").
It also has a short female M48 x 0.75 (2" filter thread) on one side, so it can also be used as an SCT male to M48 female adapter. Length of female M48 thread is approximately 2.5mm (0.1").
Baader part number: INVERT-2 or 1508020

Upgrade Baader-Celestron prism diagonalPros: Cons: Comments:
I used this to put a SCT Baader clicklock on my B-C diagonal in place of the old set-screw eyepiece holder. Both sides of this Celestron body have female 2" sct threads. Added a Baader nosepiece to finish the upgrade.(no adapter needed) It made the old sct C-B diagonal usable on my refractors. It's more functional now and looks much better too.
