Astronomik OWB-CCD Typ 3 Clip-Filter Sony Alpha 7The Astronomik OWB (Original White Balance) filter enables converted DSLR cameras without inbuilt IR-filter to be used for daytime 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.
This Clip-Filter has been sucessfully tested with all Sony Alpha 7 bodies (7, 7r and 7s in Mk I and MkII versions) and the Sony Alpha 9 body
DSLR cameras which have been converted for astronomical use by removing the inbuilt IR-filter or by substituting it with a filter with greater range for H-alpha, have a white balance that made them unable for 'terrestrial' purpose. The spectral sensitivity of the DSLR will be changed by an OWB-Filter to the former range. In other words: The OWB pretends to be the conventional built-in filter!
Special spectrum in order to adapt modified DSLR cameras (removed or substituted inbuilt IR-filter) to achieve standard colour space in digital imaging.
