ZWO filter wheel for 7 × 2" filters

With the ZWO motorized filter changer for 7 2" filters, you can easily and quickly change filters from your computer, providing you with significant convenience for both visual and photographic observations.

The filter changer has T2 or M54 (7×2" model) threads on both sides for telescope and camera attachment. It can be connected to a computer via USB 2.0 port and, after installing ASCOM's driver, it can be controlled by any compatible software. The filter changer is also powered via the USB 2.0 port, so no need for multiple cables, just a single USB cable is sufficient. The ZWO motorized filter shifter has a maximum current draw of about 120 mA @ 5V, which allows it to be operated from the USB2.0 port of a cooled CCD camera.
The package includes M54/M48 and M54/T2 adapter rings for connecting various devices.

The ZWO motorized filter changer is housed in a high quality aluminum frame, with a width of only 20 mm and a weight of 650 grams. Thanks to its slim design, it can be placed surprisingly close to the camera sensor, so there is no need to worry about vignetting even with bright binoculars.

The filter switch has 7 sockets. This number of filters is enough to satisfy the needs of the truly dedicated, serious planetary and deep-sky observer. Which filters should I use with the filter changer? For visual deep-sky observations, light pollution filters, and narrow pass (UHC) and various line filters (OIII, H-beta) that improve the visibility of emission and planetary nebulae. For planetary observations, there are a variety of colour filters to choose from to help you see low-contrast surface detail. For astrophotography, use L, R, G, B filters and/or narrow-band filters (e.g. H-alpha, OIII, H-beta).
