DSLR-Astro Conversion Filter (FBCF) for Canon 5D MkII [BA-FBCF-5DII]

BA-FBCF-5DII
$112.00 USD
Availability: usually ships within 10-14 days
Baader: BCF 2 Astro Conversion Filter CANON EOS 5D/6D MK II
Baader BCF Filters for Retrofitting Canon EOS full-frame cameras
Canon Digital SLR cameras have gained a reputation as being perfectly suitable for astro-imaging in such cases where you wish to be independent from a computer.
The cameras have many strength, 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 red structures in nebulae (H-II regions) appear much fainter in relation to the other regions than would be normal.

The solution: Change the integrated IR cut filter
By exchanging the original Canon filter for a Baader BCF2 filter, you increase the sensitivity in H-Alpha by a large factor. With this filter, the camera is then even more sensitive than the legendary Canon EOS 20DA Astro camera.
The BCF2 filter also doesn´t need the anti-aliasing layer of the original filter - Deep Sky Objects and stars are not prone to colour moire. Since the anti-aliasing layer also renders a slightly softer image, leaving it out even increases the contrast and sharpness.
Still Suitable for Daytime Imaging:
The new BCF2 filter can also be used within some limits for daytime photography. You will 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 the BCF2 filter.
High-contrast edges can show colour moiré effects, this applies mainly to buildings, grids and nets.
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.
