For the use in CCD imaging, this Opticstar 1.25" Infra-Red Cut-off Imaging Filters will exclude any IR wavelengths beyond H-alpha showing a very steep desirable curve. It is useful in greatly reducing glare in the image in general and for reducing the effect of bloated stars. The filter is mounted in a machined aluminum cell which is threaded to accept additional filters.
