With the ZWO motorized filter changer, you can easily and quickly change filters from your computer, providing significant convenience for both visual and photographic observations.
The filter changer has T2 threads on both sides for telescope and camera attachment. It can be connected to a computer via USB 2.0 port and, after installing the ASCOM driver, can be controlled by any compatible software. A 1.25" curtain adapter is included in the package.
The ZWO motorized filter changer is housed in a high-quality aluminum frame, measuring just 20 mm wide, 400 grams and small enough to fit in the palm of your hand. 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 changer can accept 8 filters with or without sockets. This number of different filters will 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, there are light pollution filters, and narrow pass (UHC) and various line filters (OIII, H-beta) to improve the visibility of emission and planetary nebulae. For planetary observations, there are a myriad of colour filters to choose from to help you see low-contrast surface detail. For astrophotography, use L, R, G, B filters or narrow-band filters (e.g. H-alpha, OIII, H-beta).
