ZWO EFW-Mini Filter Wheel for cameras from ASI and others
The motorised filter wheel is ultra compact and with its 300 g weight also extremely lightweight. Only one USB cable is enough to power up the EFW, the max power consumption is around 150 mA. So you can connect it directly to the USB2.0 hub of ZWO´s cooled ASI cameras.
The distance between the filters and sensor is only 10 mm, so there will be no vignetting with fast telescopes, even if using an ASI1600. If you use unmounted 31 mm filters, you can even use lenses up to f/2 without vignetting.
The ZWO EFW-Mini is perfect for creating L-RGB images with ASI cameras
The filter wheel offers five positions for filters - ideal for L-RGB filters + a clear opening.
