OWB - CLIP FILTER NIKON D7000 / D7100
The intention of this filter is to enable converted DSLR cameras (without inbuilt IR-filter) in order to be used for 'terrestrial' photography.
The OWB (Original White Balance) filter shifts the complete spectrum of a converted DSLR in such a manner that the camera will not be exclusively usable for astro-photography. Therefore the decision, which in former times had to be made, whether to 'victimize' a DSLR in order to exclusively use it for astronomical tasks or accept the lower sensitivity on the red end of the spectrum it is now a thing of the past and disencumber your purse, too.
