WandererAstro Snowflake SFW50 Filter Wheel, 7+1 Positions<\/h3>\n

Visit WandererAstro Snowflake 7+1<\/strong> 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<\/strong>, 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.<\/p>\n

With a thickness of 16 mm<\/strong>, 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.<\/p>\n

Unique 7+1 design<\/h3>\n

Unlike conventional 7-position filter wheels, the Snowflake has an eighth slot for an additional filter or the opaque filter supplied as standard. This solution makes it possible to produce calibration images (dark frames) directly from the setup, without having to dismantle the camera or manually shutter the telescope.<\/p>\n

    \n
  • 7 main filter slots<\/li>\n
  • 1 additional slot for filter or dark frame<\/li>\n
  • Opaque filter supplied as standard<\/li>\n
  • Ideal for automated remote sequences<\/li>\n<\/ul>\n

    Compact profile: 16 mm thick<\/h3>\n

    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.<\/p>\n

    The short distance between filter and sensor also increases the effective aperture of filters, reducing the risk of vignetting with large sensors.<\/p>\n

      \n
    • Thickness: 16 mm<\/li>\n
    • Spacers supplied to increase draft by up to 20 mm<\/li>\n
    • Perfect for systems with constrained backfocus<\/li>\n
    • Reduced vignetting on large sensors<\/li>\n<\/ul>\n

      Exceptional mechanical precision<\/h3>\n

      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.<\/p>\n

        \n
      • High-precision gear drive<\/li>\n
      • Integrated anti-backlash system<\/li>\n
      • High-resolution position sensors<\/li>\n
      • Excellent positioning repeatability<\/li>\n<\/ul>\n

        Total protection against light leakage<\/h3>\n

        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.<\/p>\n

        Internal light-proof grooves and a supplied foam gasket complete the system to ensure maximum sealing, even with certain cameras requiring additional insulation.<\/p>\n

          \n
        • Totally enclosed design<\/li>\n
        • One-piece mask to prevent light leakage<\/li>\n
        • Internal light blocking grooves<\/li>\n
        • Gasket supplied<\/li>\n<\/ul>\n

          Easy assembly<\/h3>\n

          Installation on the camera is facilitated by an ingenious design that allows the fixing screws to pass directly through the eighth slot in the disc. This solution eliminates the need to dismantle the filter wheel during assembly, and considerably reduces the risk of screws falling into the mechanism.<\/p>\n

          Enhanced mechanical rigidity<\/h3>\n

          Whereas most filter wheels rely solely on peripheral screws, the Snowflake also incorporates a central fastener. This architecture considerably improves the rigidity of the whole, and halves mechanical deformations under load.<\/p>\n

            \n
          • Reinforced structure<\/li>\n
          • Additional central screw<\/li>\n
          • Deformation reduced by approx. 50 %<\/li>\n
          • Optimum support for heavy load cells<\/li>\n<\/ul>\n

            Extended compatibility<\/h3>\n

            Snowflake has been developed to work with the majority of equipment on the market. It is compatible with cameras and optical dividers (OAGs) from all the major astrophotography brands.<\/p>\n

              \n
            • ZWO compatible<\/li>\n
            • QHYCCD compatible<\/li>\n

            • Player One APS-C and Full Frame compatible<\/li>\n
            • Compatible with most OAGs on the market<\/li>\n<\/ul>\n

              Reliable operation down to -30\u00b0C<\/h3>\n

              Thanks to its high-power motor and robust mechanical design, the Snowflake remains fully operational even in extreme winter conditions. It can operate up to -30\u00b0C<\/strong>, This makes it an ideal solution for permanent observatories and astrophotographers working in the mountains.<\/p>\n

                \n
              • Operates at temperatures as low as -30\u00b0C<\/li>\n

                Software compatibility<\/h3>\n

                The filter wheel is compatible with all major acquisition software, thanks to support for the ASCOM<\/strong>. Compatibility INDI<\/strong> is planned via a future dedicated pilot.<\/p>\n

                  \n
