This electronic filter wheel system is an upgrade on its 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 0 mm, while still maintaining the possibility of rotating the camera to any desired position.
The EFW2.2 is supplied with your choice of carousel and separate carousels are also available to allow users to change. Filter disk options include 5 x 50.8 mm, 5 x 2-inch mounted, 7 x 36 mm, and 9 x 1.25-inch mounted. This EFW2.2 system includes the carousel with 5 positions for 50 mm round filters.
The EFW2.2 has an ASCOM compliant driver, so that any compliant software can control it. Additionally, the EFW2.2 can be controlled using Atik's Artemis Capture software, for easy, simple and efficient operation.
