Motor-driven Adjustment for the TS Optics TeleFokus system
The TeleFokus system allows manual micro focusing and thereby highly precise focusing. Particularly for astrophotography, highly precise focusing is essential for good image quality. Telefok-Mot replaces manual adjustment by high-precision motorised adjustment. As a result, you do not need to touch your lens anymore, you can adjust it simply with the direction buttons of the Telefok-Mot and also control the speed of the adjustment.
The device requires a 9-volt battery to operate. (not included)
