Infra-red filter removal and installation
If greater near-infra-red sensitivity is desired, the infra-red filter can be removed. It is
important to note that removal of the IR filter can allow debris to collect on the CCD
faceplate. Please use every precaution to avoid contact with the CCD faceplate and to
keep the camera securely mounted to the optical system or capped when not in use.
