TS Telefokus - always perfect stars through optimal focusing
The Telefocus system has been developed from practical experience. It offers precise focus adjustment and fixes the focus position at the same time. An unintentional adjustment and thus blurred stars are prevented.

Focusing with stars - the challenge:
The autofocus does not work when taking images of the stars, so the lens has to be focused manually. A minimal displacement, almost just a slight touch is sufficient for turning a beautiful sharp star into an unsharp disk. Somewhen one is content with a coarse approximation according to the motto "it will fit somehow."

The Telefokus system solves this problem in a simple and effective way. A complete turn of the knurled screw rotates the knurled ring on the lens by 1 millimeter. If you turn the knurled screw by 5°, the ring of the camera lens is rotated by only 0.013 mm! You can never focus this accurately without this utility and you will notice the difference. You can then fix the position with the counter screw and even after a longer exposure time you have the guarantee that the focus is 100% kept.

Attaching the Telefok to the camera lens:
We have solved the fastening simply and elegantly. The Telefok is well attached to the lens, nothing wobbles any more. Attaching it to the lens is easy with the metal strap and a suitable screwdriver. Protective pads are included so that nothing scratches the lens. You only need to tighten the two rings slightly, this is enough to transfer the force.
Attach the first ring with the rectangular connector to the back (camera side) of the lens. The connecting piece must point to the front.
Attach the second ring to the knurled ring for lens focusing, using the two knurled screws.
The "infinity position" of the lens should be achieved by adjusting the two knurled screws.
For lenses with "autofocus", please be sure to switch off this function and switch to manual focusing.
Now you can focus perfectly.
If you want to use the lens for normal photography and do not want to remove the TelefokL, there is a simple solution. Simply remove the front part with the two screws and the lens can be adjusted roughly or via the autofocus.
The TelefokL is especially compact. This means it can remain on the lens without taking up too much space. The metal straps can of course also be shortened and the sharp corners of the straps can be masked with some adhesive tape.
