More About the Astronomik UHC Nikon XL Full Frame Clip Filter

Designed for visual deep sky observation with Nikon full frame format DSLR cameras, the Astronomik UHC XL Clip Filter allows nearly 100% of H-beta and O-III lines to get through, while blocking scattered light from other wavelengths. Plus, a second bandpass for the H-alpha line ensures it also reaches the eye. Because of the strong reduction of the sky background, gas and planetary nebulae are visible with a surprising abundance of detail. The Astronomik UHC Filter offers sufficient light for satisfactory observing of deep sky objects with smaller telescopes thanks to its high transmission.

This filter is best suited for use with instruments that have f/4 to f/15 focal ratios. Transmission loss and color shift, which can be a nuisance with other available filters, is only a concern with this UHC filter when exceptionally fast focal ratios of f/3 or less are involved. Astronomik's UHC filters work with 2" aperture telescopes and above, though work best with telescopes that have 5" apertures and above. When measured against UHC filters available from other manufacturers, Astronomik UHC filters provide users with a view containing more visible stars as well as more clear nebulae detail. In addition, because of the high optical quality of the glass, you'll be able to view stars as small pinpoints.

Astronomik UHC filter coatings are fully sealed making it impervious to moisture. The transmission characteristics of this filter are continually maintained and do not alter with time. The coatings are so hard that procuring even the tiniest of scratching would require rubbing them with sandpaper on purpose! Scratching them by mistake is simply not possible. All Astronomik filters are delivered with a long-lasting plastic storage container of supreme quality.
