Clip-Filter system for Canon EOS APS-C cameras

Do you own a Canon EOS digital camera for astro-imaging? Then you have surely encountered the following problems:

  • Large filters for large camera lens objectives are very expensive
  • If you are using an Off-Axis Guider stars will be dimmed on your autoguiding camera when a 2" round mounted filter is threaded to a corrector being ahead of the reflecting prism from the light path. 
  • For very fast (low f/ number) telescopes like the Vixen R200SS or the Takahashi “Epsilon” astrograph, a filter drawer or a filter wheel cannot be used since the distance to the corrector lenses would be changed.
  • With long exposure times your camera’s sensor chip is exposed to more dust

 

With the Astronomik Clip-Filter System you can take care of all of these problems at once!

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 genuine EF-S series lenses), all lenses (known to us) from third party manufacturers 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.)

 

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


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 filter is available as Clip-Filter for the most often used cameras for astrophotography.

Main use

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!

Other uses
None

 

The 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.

    Technical Data

    • Special spectrum in order to adapt modified DSLR cameras (removed or substituted inbuilt IR-filter) to achieve standard colour space in digital imaging.
    • Parfocal with other Astronomik filters
    • Glass thickness: 1mm
    • Completely resistant against high humidity, scratches and aging effects
    • Diffraction limited, the filter will not reduce the optical performance of your telescope!
    • Astronomik filters are delivered in a high-quality, long lasting, filter box
