This Optolong OWB (Original White Balance) Clip Filter has been designed for astro modified dSLR cameras (Canon EOS with APS-C sensor in this case), so that the camera can be used again for daytime photography as well. Astro modification of a dSLR means a removal of the IR-cut-off filter, so the camera becomes very sensitive in the near IR part of the spectrum. It is important for deep sky astro photography, but it also makes the camera unusable for daytime imaging as the images becomes reddish... One could get rid of this in post-processing, but why should one spend time with that if there is a simpler and much less time consumin solution; add a OWB filter and voila, your camera is back to normal.

Compatible with all APS-C sized Canon EOS cameras. Not for full frame cameras.
