Baader DSLR Astro-Conversion Filters for Canon EOS DSLR Cameras
Canon Digital SLR cameras have gained a reputation as being perfectly suitable for astro-imaging whenever you wish to be independent from a computer, but still want to take beautiful astrophotos.

The cameras have many strengths, but they also have a weakness: the IR cut filter which is integrated in the camera cuts off a large portion of the important red part of the spectrum - most notably of the H-alpha line. As a result, many interesting H-II regions are not within reach of the camera.

The solution: change the integrated IR cut filter
By exchanging the original Canon filter for a Baader ACF/BCF, the sensitivity in H-alpha is increased by a large factor.

Additionally the image sharpness increases clearly, as the softer rendering of the image, caused by the anti-aliasing filter and wanted by the manufacturer, is eliminated. Stray light is also reduced, as the Baader Conversion Filter includes no cemented surfaces.

Another advantage is a reduction of the chromatic aberration of optics containing lenses, as UV light is blocked more steeply.

Daytime imaging with the Baader Conversion Filter
The new Baader ACF/BCF filters can also be used within some limits for daytime photography - no additional filtering necessary. You will just need to do a manual white balance, but then the colours appear as normal. We recommend manual white balance adjustment or the setting for "artificial light" when using these filters.

Complete offer filter and conversion from Teleskop-Service
Installing the filter requires some technical skill. It should only be done by experienced persons.

You even need to do some soldering in the close vicinity of the camera´s sensor!

In addition any dust that might get between the filter and the sensor will appear sharply on the image.

We offer a Canon Retrofit Service for all customers who do not wish to do the modification themselves. You can find a direct link to further information under "recommended accessories".
