Description
This motorized filter holder wheel allows you to position 5 filters in front of your camera and change them quickly thanks to a computer (or the ASIAIR control unit).The very thin design (20 mm backfocus) of this filter wheel allows you to position the filters as close as possible to your sensor to limit vignetting (darkening of the edges of the image).
Its motor consumes very little electricity, allowing it to be powered directly by USB through your camera.
This filter holder wheel ZWO EFW-25 works with all software on the market through an ASCOM driver. High quality aluminum construction machined by CNC (Computer Numerical Controlled Machine).High precision stepper motor, which guarantees constant rotation and stable operation even during long imaging sessions.

New generation
ZWO is continuously improving its products and its EFW filter wheel range has just received a slight facelift:
Redesigned design: improved mechanics ensuring smoother and more uniform rotation.
Light Leakage Protection: New light seals added to the two side connection points that create an additional optical barrier and help maintain sharp, uniform images during extended uses.
Fully enclosed motor compartment: The motor block is now completely sealed, improving light isolation and weather resistance for more stable operation over time.
Improved exterior design: Subtly optimized construction for a more harmonious appearance and neat finish.
True plug-and-play design: No driver installation required.
Lightweight and robust: CNC-machined aluminum alloy housing for a lighter and more rigid structure.internal filter carousel is made of 6061 aluminum alloy, which reduces weight while maintaining excellent strength and stability.a in a compact and durable design, engineered for smooth and reliable operation.
Automated filter change: Bi-directional motorized drive for each filter wheel with precise indexing of positionn.Asociado to control software such as ASIAIR (sold separately), each EFW allows for automatic filter changes during a scheduled imaging session, enabling a completely autonomous, hands-free imaging session.
