Used Atik EFW2 1.25" 9-Position Filter Wheel

We're pleased to introduce a new motorized filter wheel, with multiple filter capability. This new wheel employs exchangeable filter disks, allowing for multiple combinations, and has large 54 mm openings on both sides. With these features, the ATIK EFW2 can easily support sensors up to full frame (35 mm) format. 

The ATIK EFW2 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 maintaining the possibility to rotate the camera to any desired position. Total extra backfocus needed will be only 22 mm.

On the software side, the EFW2 has an ASCOM driver, so that any compliant software can control it. Comes with Artemis Capture software, for easy, simple and efficient operation.

ATIK Electronic Filter Wheel Features:

  • Closed design eliminates light leaks even in the presence of light-pollution
  • Central support maintains rigidity even when using heavier cameras
  • Magnetic sensors allow precise positioning without the use of LEDs
  • Battery power connector (12V Cigarette lighter cable) and 3 m USB cable
  • Extremely affordable price!
  • 1.25-inch, 9 Position Filter Wheel

Please Note: ATIK filter-wheels include a 2-inch nosepiece. For customers wanting to use this interface (2-inch slip-fit) with a focuser or visual back, no other parts are needed to attach the filter-wheel to the telescope. Customers wanting/needing to use a threaded interface on the telescope-side of the filter-wheel will need to either use M54x1 threaded adaptation from another source or the ATIK M54/M42 adapter, to reduce the interface to T-Thread.
