Electronic Filter Wheel to add colour to your images

An upgrade on it's predecessor, The Atik EFW2.2 features a new mechanical location system for indexing the filter. This ensures that filters are always in precisely the same position which is of great benefit for flat field framing. Ensuring that flat field frames display exactly the same optical characteristics is essential to ensure that anomalies such as dust can be handled and removed accurately.

The EFW2.2 also features a slick design, with a slim and lightweight profile. For example, the distance between any Atik camera and the wheel itself is 0mm, while still maintaining the possibility of rotating the camera to any desired position.

Filter disk options include 5x50.8mm, 5x2” mounted, 7x36mm and 9x1.25” mounted. Regarding software, the EFW2.2 has an ASCOM compliant driver, so that any compliant software can control it. Additionally, the EFW2.2 can be controlled using our Artemis Capture software, for easy, simple and efficient operation.

The EFW2.2 is supplied with your choice of carousel and separate carousels are also available to allow users to change.
