  • The Astronomik OWB (Original White Balance) Type 3 Filter is designed for Canon EOS digital SLR cameras that have been modified for astronomy imaging and is presented in a Canon EOS clip format.
  • For 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.
  • The Astronomik OWB (Original White Balance) Type 3 Filter clips into any Canon EOS Digital SLR camera and restores the ability of the camera to be used for terrestrial photography, like the original standard equipment filter.
  • The spectral sensitivity of the DSLR will be changed by an OWB-Filter to the former range.
  • The Astronomik OWB (Original White Balance) Type 3 Filter coatings protect amazingly well against scratching, aging, and humidity.

Astronomik OWB (Original White Balance) Filter - Type 3 - Canon EOS Clip

The Astronomik OWB filter would usually not be designated as an "astronomical" filter. The intention 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. The OWB EOS Clip filter fits in all Canon cameras of the type series 20D(a)-40D, 300D-450D and 1000D.

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 pretend to be the conventional built-in filter!

About the Astronomik Clip-Filter System....

The patented Astronomik Clip-Filter System is black anodized aluminum and laser-cut on state-of-the-art modern machines. It can be inserted within seconds directly into the EOS camera body. There are no changes necessary and all lens functions (focus, screen, image stabilization) remain functional!

Almost all Canon system lenses (with the exception of the EF-S series) and all M42 and T2 lens adapters, can be used with the Astronomik Clip-Filter System. The Clip-Filter System also acts as an outstanding dust shield, which prevents the possibility of dust settling on the sensor during long time exposure (The MC-Clear filter does not have a filter effect and only acts as a dust shield.)

Note: For Photographers interested in daylight IR-Photography a "MC-modification" is possible for some cameras. If you are interested in this, please send us a short mail. We will give you more details. The "MC-modification" gives you no advantage for normal astrophotography! The Astronomik Canon EOS clip is not suitable are cameras offered before 2003 and all varieties of the Canon EOS 1D and Canon EOS 5D.

Note the EF-S lens warning
There's a big problem with this filter -- it doesn't work with the EF-S lens series. Why is this a problem? Because EF-S lenses are the primary lenses for the small-sensor EOS cameras, which this filter clip is designed for.

What makes this worse is that although you can alternatively use an (expensive IR filter on the front of the lens, front-mounted IR filters don't work with wide-angle lenses, due to the high incidence angle. But wide-angle lenses are exactly where the EF-S series is most necessary! It's difficult to find wide-angle alternatives in the normal EF lens series, due to the small-sensor-EOS 1.6 focal-length multiplier.
