Product description

Accurate manufactured T2 extension ring excluding T2 external thread. This extension tube is a real problem solver for fine tuning.

Specifications:

  • Adaptation on telescope site: T2 Internal thread (M42x0.75)
  • Adaption on camera site: T2 External thread
  • Clear aperture 39mm
  • Black anodized

This particularly versatile solution consists of three parts:

  • Base part with long T2 external thread
  • Narrow counter ring with knurled handle
  • Connection piece with T2 internal thread and T2 connection

Simply turn the connecting part until the adaptor has reached the desired length and then lock the position with the counter ring. You now have a permanent T2 extension in exactly the length you require.

TS Optics is a brand of Teleskop-Service.

Bad quality

The threads are so sloppy fit, that it barely holds itself together. Can't recommend this.
