Snowflake 8 x 36mm WandererAstro low profile filter wheel

Snowflake SFW36S

Main features

• 8 filter slots (configuration 7 + 1) for unmounted or included dark filters
• Holders: unmounted filters Ø36 mm, thickness: 1,9-3,5 mm
• Compatible with: ZWO, QHYCCD, ToupTek, PlayerOne (APS-C and full frame) and most OAG systems
• Fully enclosed housing prevents dust, light leakage and damage.
• Body thickness: only 14 mm, ideal for short back focus systems
• Weight: 555 g
• High-torque stepper motor, operates reliably down to -30 °C

Designed for high-precision imaging:

Using a gear-driven rotation system , enhanced with an anti-backlash damping mechanism and high-resolution sensors , the SFW36S ensures precise and repeatable positioning for filter alignment, critical for consistent flat-field calibration.

The center mounting screw adds superior structural rigidity, reducing deflection by 50% compared to conventional filter wheels.

Advanced structural design:

• One-piece filter mask : fewer screws are required, preventing accidental drops in the optical path
• Foam light blocking ring included : to seal against cameras that lack their own gasket
• Internal staggered grooves - ensure total light blockage
• Through-hole mounting in slot 8 : allows direct connection to the camera without removing the filter disk

Quick installation and modular configuration:

Thanks to the clever design of slot 8, the camera can be mounted directly to the wheel without removing the filter disk , speeding up assembly and minimizing contamination or handling errors.
