Where to find STL thread extension tubes.

[cventer]

I am looking for some extension tubes to adjust the distance of my STL threaded camera from the optimal focus plane.

Anyone got any they don't want or ideas where to get some?

Basically after male to female adapters

Have u looked at optcorp they have quite a few stl adapters there ?

Chris also consider Precise Parts in the states. They custom make adapters and all the ones I have had made are superb

If you mean 2.156-inch diameter extension tubes, then PreciseParts can make them. Just use the online Adapter Builder and select generic-caps-extensions on the left side and SBIG on the right, then Extension Tube or Spacer on the left, the length you want in the middle and SBIG STT Camera with 2.156-24 thread on the right. It's a rather expensive way to obtain an extension though.
