Focusing can be quite time consuming process even with the Bahtinov mask (especially with narrowband filters). Additionally, focus can shift with temperature change during the night. We have solved this for you with our special rails mounted autofocuser kit, which can compensate for the front movement of the lens during focusing.
The autofocusing motor rests on the special trolley, connected to the rails. This keeps autofocuser pulley in line with lens focusing ring and enables a balanced, compact solution.
