ZWO 5-Position EFW for 2" Filters (ZWO-EFW-5X2)
This ZWO EFW filter wheel is electronic, powered using the included 2m USB2.0 cable. Weighing in at only just over 1 lb (500g) and with a 20mm thickness, this filter wheel is a lightweight and effective way of reaching your imaging goals.
With 5 positions, this filter can fit 2" threaded filters or 50.4mm (±0.5mm) unmounted filters. The reliable stepper motor comes from NPM, Japan and will provide reliable quality and performance during use.
If you have been looking for a way to switch filters during your astroimaging session without messing with the setup and risking that crisp, clear focus you worked so hard to achieve, this ZWO EFW Filter Wheel is made to aid in switching between filters during sessions, allowing a relatively hands off approach.
When it comes to powering the EFW, there is no need for multiple cables, just the one USB cable provided. The maximum power consumption of this ZWO EFW is approximately 120mAh @ 5V, which can be provided by the ZWO's cooled CCD camera (not included) USB2.0 port. The control modes are ASCOM and SDK.
ZWO's filter wheel body is CNC milled from an aircraft graded aluminum block. The wheel can be rotated either clockwise or counter clockwise, so filter selection is a breeze. If connected to the ASI6200 camera from ZWO, the distance from filter to sensor is about 18mm.
