Omegon Pro EFW-L 7×2” Filter Wheel - Unlimited versatility for serious astrophotography
The Omegon Pro electronic filter wheel EFW-L takes your astrophotography to the next level. At the touch of a button, you change filters at lightning speed, without vibrations or manual intervention. This allows you to make the most of every minute under the stars and keeps your setup perfectly aligned for razor-sharp images.
Fast, accurate and reliable
The advanced mechanical positioning system ensures that each filter is placed in exactly the right place. You don't waste time searching or correcting. The compact design supports filters up to 7 mm frame height (without threads), allowing most common 2″ filters to fit without problems.

Seamless integration into your setup
Thanks to M54 internal threads on both the front and rear, this filter wheel fits perfectly with telescopes with large focusers. With the included adapters, you can also easily connect M48 and T2 systems. The very short optical length of only 20 mm helps you avoid focusing problems even in complex imaging trains.

Built for intensive use
The rugged aluminum housing is designed for long-term use under demanding conditions. Power and data run through a single USB 2.0 cable, keeping your cable management organized. With ASCOM and INDI support, the filter wheel works smoothly with virtually all popular astrophotography software.
