Every day our eyes catch the light of our memories – time spent with family, the journey to work, a special holiday, a beautiful sunset or a dark starlit night. Each image captured is a picture drawn in light – a photograph: only to be lost in our minds or forever forgotten. Nearly two hundred years ago a small group of amateur scientists achieved what had eluded mankind for centuries – the ability to capture a permanent record of an image seen by their own eyes – a moment in time frozen onto a surface. They had discovered Photography. They were the ‘Catchers of the Light’.

Full Moon in ir 850nm

 

An interesting view of the full moon at 850 nm with the ZWO IR 850 filter.

this filter allows the passage of infrared light at 850 nm, which can be useful for cameras sensitive to the infrared spectrum. This helps isolate specific details and features in planetary and lunar objects that are more visible in infrared light.

By using the IR 850nm filter, interference from visible light is reduced, which can improve the contrast and sharpness of images, especially under conditions of atmospheric turbulence or in the presence of ambient lighting.

If you are using a color camera such, you can use it as a monochrome camera with this filter by setting the white balance parameters (WB_R and WB_B) to 50, so that no white balance is applied and you can fully exploit the sensitivity in the infrared spectrum.
