Visit WandererAstro Snowflake 7+1 is a top-of-the-range motorized filter wheel designed for demanding astrophotographers looking for impeccable mechanical integration, minimal thickness and excellent light-tightness. Thanks to its innovative 8 positions, One of which is dedicated to an additional filter or an opaque filter for darks, it offers a level of flexibility rarely seen on the market.
With a thickness of 16 mm, the Snowflake SFW50 offered here is one of the most compact filter wheels available. This feature is particularly useful for setups where backfocus is limited or when accessories such as a field rotator (CAA) or tilt adjuster need to be added.
Unlike conventional 7-position filter wheels, the Snowflake features an eighth slot that can accommodate an additional filter or the opaque filter included with the unit. This solution allows you to capture calibration images (dark frames) directly from the setup without having to remove the camera or manually cover the telescope.
The Snowflake's main advantage lies in its extremely slim profile. Its mechanical thickness of 16 mm allows for maximum backfocus for correctors, reducers, or additional accessories.
The short distance between the filter and the sensor also increases the effective aperture of the filters, thereby reducing the risk of vignetting with large sensors.
The wheel uses a gear drive combined with a damped anti-backlash system. This design ensures extremely precise and repeatable filter positioning, guaranteeing perfect consistency of flats and calibrations over time.
Snowflake adopts a completely enclosed architecture with no visible motors or electronics. Its exclusive one-piece mask eliminates potential stray light paths, while offering a particularly meticulous finish.
Internal light-proof grooves and a supplied foam gasket complete the system to ensure maximum sealing, even with certain cameras requiring additional insulation.
Installation on the camera is made easier thanks to an ingenious design that allows the mounting screws to pass directly through the eighth slot in the disc. This solution eliminates the need to remove the filter wheel during assembly and significantly reduces the risk of errors or screws falling into the mechanism.
While most filter wheels rely solely on peripheral screws, the Snowflake also incorporates a central fastener. This design significantly improves the overall rigidity of the assembly and cuts mechanical deformation under load in half.
The Snowflake was designed to work with most equipment on the market. It is compatible with cameras and optical splitters (OAGs) from the leading astrophotography brands.
Thanks to its high-powered engine and robust mechanical design, the Snowflake remains fully operational even in extreme winter conditions. It can operate up to -30°C, This makes it an ideal solution for permanent observatories and astrophotographers working in the mountains.
The filter wheel is compatible with leading data acquisition software thanks to its support for the standard ASCOM. Compatibility INDI is planned via a future dedicated pilot.
The SFW50 listed on this product page is 16 mm thick. It accommodates both mounted 2-inch filters and unmounted 50 mm filters. Check the dimensions and interfaces of your filters and camera before installation.
