Astronomik OWB Type 3 Clip-Filter EOS R XL (Original White Balance)
The OWB (Original White Balance) filter shifts the complete spectrum of a converted DSLR or Mirrorless camera 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 or Mirrorless camera 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.
The OWB filter is available as Clip-Filter for the most often used cameras for astrophotography.
Main use
Mirrorless 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 Mirrorless camera will be changed by an OWB-Filter to the former range. In other words: The OWB pretend to be the conventional built-in filter!
Other uses
None
The OWB filter would usually not be designated as an "astronomical" filter. The intention is to enable converted Mirrorless cameras (without inbuilt IR-filter) in order to be used for 'terrestrial' photography.
