TS-Optics T2 Helical Focuser and variable T2 Extension Adapter
Many telescopes, like Schmidt-Cassegrains or Maksutovs, offer a rather coarse focus adjustment. This helical focuser offers a clearly more precise and comfortable focusing. Simply twist the knurled ring and achieve perfect focus with your telescope or telephoto lens. The camera does not rotate when adjusting, so image orientation is always maintained.

Simply screw the TS helical focuser onto the T2-thread of your telescope or use the optional push adapters for attaching the focuser to the 2" or 1.25" receptacle. The adapters can be found in the accessories section.

You can also thread the helical focuser to the T2 mount of your telephoto lens for precise focusing of eyepieces or compact cameras.

Adapting cameras or eyepieces to the helical focuser:
In the accessories section, you can find most important connection adapters for the T2-thread of the adapter/focuser. With suitable adapters, you can use DSLR cameras, but also CCD cameras or eyepieces.
