Orion Filters

Orion offers a selection of competitively priced astronomical filters for both visual and photographic applications. Note that the extra narrowband filters are strictly for imaging applications. The Orion UltraBlock filter is a particular favorite for visual observation of emission nebulae. Some of these filters are labeled as light pollution filters, which we think is rally a disservice to the hobby. While it is true that they will enhance the view of emission nebulae under light polluted skies, there really are no filters for enhancing the view of galaxies or other broad spectrum targets.
