Thanks Patrick, no luck so far with the Vixens.
Dennis, the Baader-Kunama adapter won't happen overnight but it will happen !!!!
Barry, thanks for the PM reply here is another pic to explain a bit more:
The Baader ClickLock pictured internal thread is standard 2'' SCT and measures internally at 49.55mm
The middle piece is the Tak Extension tube which would be cut on the right side of the cable tie leaving about 12mm to the step up, that section is at the moment 52mm OD and 46.25mm ID
The ring on the right is a Baader part for attaching filters to the Eyepiece holder, it has the correct thread, measuring 50.75mm OD of thread.
This is the thread that the middle bit needs to end up, with the thread running from the right of the cable tie to as close to the step-up as possible.
Cheers,
Matt
