More About the Astronomik UHC Canon EOS Clip Filter
This Astronomik UHC EOS Clip Filter has been specifically designed for visual deep sky observation with Canon EOS cameras. This filter simultaneously allows nearly 100% of H-beta and OIII emission lines to pass through, plus a second bandpass to guarantee that the H-alpha line also makes it to your eye, while obstructing unwanted light from other wavelengths. A remarkable amount of gas and planetary nebulae detail is now visible due to the strong sky background reduction. In addition, this filter's high transmission allows it to supply enough light to efficiently view deep sky objects, even with smaller telescopes.
Best-suited for telescopes featuring a focal ratio range spanning from f/4 to f/15. With the Astronomik UHC Filter, transmission loss and color displacement are only an issue when working with ultra fast focal ratios of f/3 or less, unlike other filters on the market. Astronomik UHC filters work with 2" aperture instruments and above, but work particularly well with 5" apertures and larger. UHC filters sold by other manufacturers are lacking as far as the quantity of stars or nebula detail they show when compared to Astronomik UHC filters. Furthermore, the superior optical quality of the glass on this filter allows stars to be viewed as tiny pinpoints.
Fully sealed coatings on this Astronomik UHC Filter shield it from the impact of external moisture. Astronomik UHC filters maintain their transmission characteristics indefinitely. The coatings are so tough that scratching them by accident would not be possible. In fact, to obtain even the finest of scratching, you would have to purposefully rub these coatings with sandpaper! Like all Astronomik filters, this UHC filter is delivered with a durable, high-quality plastic filter case.
Astronomik Clip Filter System
Astronomik's patented Clip-Filter system has been designed from black anodized aluminum and laser-cut on up-to-date modernized machines. Within seconds, it can be introduced directly into the EOS camera body. No adjustments are required and all lens functions like focus, screen, and image stabilization, remain operational! With the exception of the EF-S series, all Canon system lenses plus all M42 and T2 lens adapters are useable with the Astronomik Clip-Filter system. This Clip-Filter also serves as an effective dust protector, keeping dust from collecting on the sensor during extended exposures.
