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 particularly elegantly. The Telefok is well attached to the lens, nothing wobbles.
Attach the first ring behind the knurled ring for lens focus.
Attach the second ring to the knurled ring for lens focus.
The rectangular connecting piece must come between the two jaws of the counterpart with the M4 knurled screws.
Be sure to turn off the lens autofocus (if present) and switch to manual focus.
And from now on you can focus perfectly.
If you want to use the lens for normal photography and do not want to disassemble the TelefokL, there is a simple solution. Simply remove the rectangular connector and the lens can be adjusted manually or via autofocus.
