The ZWO Electronic Filter Wheel weighs only 400 grams, it is CNC machined and the optical thickness is only 20mm. This model can take 8 x 1.25" mounted or 31mm unmounted filters.

The power absorption of the EFW is only 120mAh @ 5V so any USB cable can power it up.

The distance between the filter and sensor of the Pro cameras like the ASI1600 is circa 10mm. This close distance prevents any vignetting with 1.25" filters for telescopes up to f/5. For f/2 lenses/telescopes it is necessary to use 31mm filters.
