In stock (can be backordered)

The ASKAR FMA135 is a premium optical instrument that features a 30mm ED triplet objective to deliver superb image quality for astronomical and terrestrial imaging. It also works as a finder/small telescope/guide scope.

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.
