Astronomik OWB Filter - Type 3 - EOS Clip
Astronomik OWB Filter - Type 3 - EOS Clip
- The Astronomik OWB Filter - Type 3 - EOS Clip (Original White Balance) Filter is designed for Canon EOS digital SLR cameras that have been modified for astronomy imaging and is in a Canon EOS Clip mount
- Designed for DSLR cameras which have been converted for astronomical use by removing their 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 (modified) DSLR will be changed by installing an OWB-Filter to the original Canon-designated range
- Coatings protect amazingly well against scratching, aging, and humidity
- Diffraction limited, the filter will not reduce the optical performance of your telescope
More About the Astronomik OWB Filter - Type 3 - EOS Clip
The Astronomik OWB filter would usually not be designated as an "astronomical" filter. The intention is to enable converted DSLR cameras (without a built-in IR-filter) to be used for conventional "terrestrial" photography. DSLR cameras which have been converted for astronomical use by removing their IR filter or by substituting it with a filter with greater range for H-alpha, have a white balance that made them unusable for terrestrial purposes. The spectral sensitivity of the DSLR will be changed by an OWB-Filter to their original range.
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, 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 is now a thing of the past. The OWB EOS Clip filter fits in all Canon cameras of the series 20D(a)-40D, 300D-450D, and 1000D. This OWB Filter Type 3 is parfocal with other Astronomik filters.
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, plastic filter box.
Astronomik Clip Filter System
Astronomik's unique Clip-Filter system features full black anodized aluminum construction and has been laser-cut on state-of-the-art machinery. Inserts directly into a Canon EOS DSLR camera body in mere seconds with no adjustments required. Focus, screen, image stabilization, and all other lens operations will continue to function! Apart from the EF-S series, all Canon system lenses, along with all M42 and T2 lens adapters, support the Astronomik EOS Clip Filter. This system also makes for an excellent dust protector as it keeps dust from accumulating on your sensor when performing long exposures.
