Atik EFW3 Electronic Filter Wheel for Large Format Cameras with 7 Positions for 50.8mm Unmounted Filters

The Atik EFW3 is a lightweight, compact seven-position electronic filter wheel designed for large format filters. This filter wheel is produced from durable aluminum similar to the EFW2 5-position filter wheel. Atik's EFW3 is just 9" by 8" and has a weight of only 1.8 lbs. The back focus is 41.5mm when the front plate is in place. You have the option to remove the plate to achieve a 34.5mm back focus.

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 50.8mm unmounted filters. If you prefer using 2" mounted filters, you'll want to buy the .

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.
