The ZWO 1.25″ IR 850nm Pass Filter is suitable for IR sensitive cameras. You don’t need to debayer and get the full resolution of this sensor when use it with a color camera such as the ZWO ASI224MC or ASI185MC, because the QE responce  of sensor beyond 850nm is all the same (i.e. infrared light passes through the Bayer colour layer). So you can use a color camera as mono camera with this filter, just don’t forget to keep the WB_R and WB_B settings to 50 (no White Balance applied).

ONLY FOR PHOTOGRAPHIC USE! This filter is not suitable for visual observations as humans won't see anything in that part of the spectrum.

To see the unseen: ASI224MC+850nm IR filter + 2.1mm lens. Click on the image for higher resolution. (only for demonstration purposes, filter is being hand-held in front of the lens...)

The difference that the filter makes when imaging the moon is incredible, everything appears sharper and it can even give sharp contrasty lunar images in daylight with black skies. I am going to try it on Venus as soon as its in a suitable position. Jupiter looks strange with very different details becoming noticeable but unfortunately the noise is increased.
