ZWO EFW Mini 5x1.25 inch Filter Wheel: The Compact Wheel for the 1.25 inch Mono Workflow<\/strong><\/h2>\n\n\n\n

The EFW Mini is the entry-level point for automated filter changing: five positions for 1.25-inch or 31 mm filters in a housing that is only 20 mm thick and weighs 300 grams. The silent stepper motor changes filters without touching the setup and without disturbing the focus.<\/p>\n\n\n\n

Because the filters are only 10mm from the sensor, the image remains free of vignetting, even with extremely fast optics down to f\/2. Power and control are supplied via a USB 2.0 cable; a separate power supply is not needed.<\/p>\n\n\n\n

Small wheel, complete workflow<\/h4>\n\n\n\n

Five positions cover LRGB plus a narrowband filter, or three narrowband channels with luminance and spare. Exactly enough for the complete mono workflow on cameras with sensors up to 4\/3 format.<\/p>\n\n\n\n

The T2 connection (M42 x 0.75) is on both sides; a 1.25 inch barrel is included for mounting in a focuser.<\/p>\n<\/div>\n<\/div>\n\n\n\n

At home in the ecosystem<\/h4>\n\n\n\n

The wheel is recognized by ASIAIR, NINA, and all common capture software, and works directly with ASI monochrome cameras. Filter changes are performed on command or fully automatically within a capture plan.<\/p>\n\n\n\n

With its low weight, this is also the logical choice for travel setups.<\/p>\n<\/div>\n<\/div>\n\n\n\n
