ZWO EFW 7×2 inch filter wheel for ASI Mono cameras

ZWO EFW 7x2 inch filter wheel for ASI Mono cameras: the complete palette in full-frame format

The EFW 7×2 inch is the maximum filter wheel for full-frame mono cameras such as the ASI6200MM Pro: seven positions for 2-inch or 50.4 mm unmounted filters. This allows you to load LRGB and H-alpha, OIII, and SII simultaneously, for complete projects without changing a filter.

Despite the seven large positions, the wheel remains 20 mm thick and approximately 650 grams light. The silent NPM stepper motor positions accurately and repeatably, and the low power consumption is completely supplied via USB.

Seven channels, zero compromise

Nighttime projects in LRGB plus Hubble palette run fully automatically: the capture plan swaps channels without image shift or loss of alignment, and flats remain valid because each filter returns exactly to its position.

On full-frame sensors, the 2-inch format prevents any vignetting, even with fast astrographs.

The regular partner of the 6200MM

Together with the ASI6200MM Pro and the 2-inch filter sets, this wheel forms the reference train for mono on full-frame. Integration with ASIAIR and NINA is complete.

Suitable for both threaded 2-inch and unthreaded 50.4 mm filters.

For whom yes, for whom no

Hello full-frame monophotographers who want the complete seven-channel palette permanently loaded.

Not who can manage with five filters; the compact 5×2 inch wheel is then more cost-effective.
