TS - T2 Extension Tube variable length 20.5 to 30 mm

TS - T2 Extension ring - variable length 20.5 to 30 mm

For a seamless fine tuning of T2 distances - always reproducable. T2 extension tubes are intended for reaching the optimal distances e.g. with correctors, field flattners 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 (M42 x 0.75).


This is how the T2 extension works:

The tree parts:

• 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 your needed length.
