• The ZWO 1.25-inch IR 850nm Pass Filter is suitable for IR sensitive cameras. This filter is great for lunar and planetary imaging systems. It greatly reduces seeing conditions by blocking all wavelengths up to 850 nanometers on the spectrum, allowing only IR light to pass. You can photograph wavelengths where seeing is significantly lower.

  If using a color camera, you don’t need to debayer and get the full resolution. Most Color ZWO cameras’ QE response is 850nm. So you can use a color camera as a monochrome camera with this filter, just don’t forget to keep the WB_R and WB_B to 50 (no White Balance applied).
