The ZWO EFW 2-inch filter wheel is specially designed for astrophotographers working with mono cameras such as the ASI 6200MM Pro. This filter wheel allows quick and precise switching between different 2\u201d color and fog filters without manual intervention - ideal for LRGB, narrowband or multispectral photography.<\/p>\n\n\n\n

Key benefits<\/strong>
\u2713 Supports 5 filters of 2\u201d or 50.4 mm (unmounted)
\u2713 No vignetting, even with full-frame sensors or fast telescopes
\u2713 Ultrathin design of only 20 mm thick
\u2713 Precise stepper motor from NPM for quiet, precise filter changes
\u2713 Lightweight aluminum body (approx. 500-650 g)
\u2713 USB connection with low power consumption - no external power supply required<\/p>\n\n\n\n

What makes this filter wheel special<\/strong>
This compact filter wheel is designed for serious astrophotography with mono cameras. Thanks to the slim CNC-machined design<\/strong> (only 20 mm thick) it fits seamlessly between your telescope and camera without losing optical length. Despite its compact size, there is room for five large 2\u2033 filters<\/strong>, which is more than sufficient for most photographic workflows (e.g. LRGB + Ha\/OIII\/SII).<\/p>\n\n\n\n

Thanks to the precise stepper motor from Japanese manufacturer NPM<\/strong> changes the wheel silently and extremely precisely, without backlash or misalignment. This motor is also used in professional equipment because of its reliability.<\/p>\n\n\n\n

Compatibility and connection<\/strong>
The filter wheel is ideally suited for the ASI 6200MM Pro<\/strong> and other full-frame mono cameras from ZWO. Connections are available in M54x0.75, M48x0.75 and T2 (M42)<\/strong> - all screwed in internally - so you can flexibly link to your existing setup. Power is supplied via a single USB 2.0 cable and requires no external power supply.<\/p>\n\n\n\n

Assembly and delivery<\/strong>
The filter wheel can be screwed directly onto the ASI6200MM Pro. For instructions on the exact mounting method, please refer to the official manual of ZWO<\/a>.<\/p>\n\n\n\n

Included are:
- USB cable
- Filter masks
- Threaded adapters
- Fastening screws
- Screwdriver<\/p>\n\n\n\n
