... for a seamless fine tuning of T2 distances - always reproducable

TS Optics - variable T2 extension 20.5 - 30mm

This picture shows the inner- and outermost position

T2 extension tubes are intended for reaching the optimal distances e.g. with correctors, field flatteners or reducers. They are also needed for eyepiece projection. This variable T2 extension allows to fine tune the distance by the fraction of a mm.
The threads (male and female) are the international used T2 threads (M42x0,75).

This is how the T2 extension works:

The three parts (from left to right):

-- Base part with long male T2 thread
-- Small counter ring
-- Connection part with female T2 thread

Turn the connection part as long until the desired length is reached. Then, tighten the counter ring. Now you have a fixed T2 extension exactly fitting to your needed length.
