ZWO 1.25″ IR 850nm Pass Filter suitable for IR sensitive cameras. You don’t need to debayer and get the full resolution of this sensor when use it with a Colour camera such like ASI224MC or ASI185MC. Because the QE response of sensor beyond 850nm  is all the same. So you can use a colour camera as mono camera with this filter, just don’t forget to keep the WB_R and WB_B to 50 (no White Balance applied).
