ZWO Compact Filter Wheel EFW 2 inch: five 2-inch positions for full-frame mono<\/strong><\/h2>\n\n\n\n

This compact EFW wheel brings automatic filter changes to full-frame mono cameras like the ASI6200MM Pro. Five positions for 2-inch or 50.4 mm unmounted filters cover standard workflows: LRGB plus a narrowband filter, or the SHO trio with luminance and a spare.<\/p>\n\n\n\n

Despite the large filter size, the wheel is only 20 mm thick, keeping the optical train short and rigid. The NPM stepper motor switches silently and precisely; power supply and control run via USB without an external adapter.<\/p>\n\n\n\n

Large glass, no shadow<\/h4>\n\n\n\n

On full-frame sensors, 2 inch is the only filter size without vignetting. This wheel positions each filter repeatably and exactly in front of the sensor, so flats remain reliable across the entire project.<\/p>\n\n\n\n

The CNC-machined aluminum housing weighs approximately 500 to 650 grams.<\/p>\n<\/div>\n<\/div>\n\n\n\n

In the ecosystem<\/h4>\n\n\n\n

Fully integrated with ASI cameras, ASIAIR, and capture software like N.I.N.A.: filter changes are included in the fully automated imaging plan, night after night.<\/p>\n\n\n\n

Anyone who needs seven positions for LRGB and fully narrowband chooses the larger EFW 7\u00d72 inch.<\/p>\n<\/div>\n<\/div>\n\n\n\n
