Motorisiertes Filterrad EFW 7x36mm II

The motorized filter wheel allows you to change the filter via the camera control. That's comfortable and non-contact. The focus is retained. The filter change can be done automatically.
The control and power supply is easy via the USB 2.0 hub of the camera.

The filters are only 10 millimeters away from the sensor, so there is no edge shading even with high-power telescopes.
