Teleskop Service 90° Polar Scope Diagonal

[Atmos]

Unused:
Bought this a while back due to some comments on CN about it fitting the eye piece of a finder on a Mewlon. The post was 12-18 months old at the time and I believe TS changed the size of the hole and it doesn’t fit in the finder :(

Bought it for $100 Euro, selling for $100+postage if needed

Colin, It's not much use if I can't tell if it will fit my polarscope... what's the inside diameter of the bit that fits over the eyepiece ?
Can you measure this accurately to 0.1mm with vernier callipers - not just a ruler ?

It needs to be accurately centred over the exit pupil of the eyepiece otherwise it won't work...

I am not at home at the moment but I’ll measure it with some digital micrometers tomorrow afternoon.

Measured the ID with a digital micrometer and it came in at 25.9mm
