ZWO Filter Wheel for 8x 1.25" mounted or 8x 31unmounted filters

ZWO Motorised Filter Wheel for cameras from ASI and others

The motorised filter wheel is compact and with less than 400 grams (without filters) aalso lightweight. USB2.0 is sufficient for powering; the max power consumption is around 150 mA. so you can connect the USB cable directly to the USB2.0 hub of the cooled ZWO 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 annoying vignetting.
