    Atik EFW3 Electronic Filter Wheel for Large Format Cameras with 7 Positions for 2" Mounted Filters


    The Atik EFW3 Electronic Filter Wheel is a lightweight, large format filter wheel with 7 positions and machined from sturdy aluminum, similar to the 5-position EFW2. The Atik EFW3 is roughly 9" in length and 8" in width, weighing just 1.8 pounds. With the front plate, the back focus is 41.5mm, however, you are able to remove the plate to achieve a back focus of only 34.5mm.

    Because the EFW3 is designed for cameras with larger sensors, it can carry seven 2" filters in either a mounted or unmounted format. This version of the EFW3 comes with the filter disk for seven 2" mounted filters. If you prefer using 50.8mm unmounted filters, you'll want to buy the EFW3 with the filter disk for seven 50.8mm unmounted filters.

    The Atik EFW3 Electronic Filter Wheel is compatible with any Atik camera. In fact, those astrophotographers who use the Atik 16200 can attach the EFW3 directly to the camera or remove the front plate to cut down on back focus. Other Atik cameras can be attached via an included M54 or M42 adapter.

    A full ASCOM driver is included with the EFW3, allowing you to use any control software that is ASCOM-compliant. You can also use Atik's Artemis Capture software for control of the EFW3 if you so choose.
