Astronomik and Gerd Neumann Filters

Astronomik filters are a valuable complement to your telescope optical equipment train. They are used worldwide by professionals and advanced amateurs because of their superior quality.

Superior Substrate: Astronomik filters consist of a precision polished substrate on which the actual filter, in the form of very thin (dichroic) interference layers, is applied. Because of these high quality measures Astronomik filters will in no way reduce the performance of your optical system. And contrary to common experience with other manufacturers´ filters, with Astronomik filters stars remain fine needle points of light! 

Coating: Astronomik filters consist of up to 130 layers deposited on top of the completely transparent carrier glass. These layers work as the actual filter and as an antireflective coating. 

Durability: Astronomik filters are completely scratch resistant, and not sensitive to moisture, dew, or high humidity. With others’ filters, after a few years, you start to notice their filter is no longer up to its full capability. Not so with Astronomik filters which maintain their ‘brand new’ transmission specifications year after year.

Parfocal Filters: All Astronomik CCD Filters are parfocal. When changing filters, the focal point will not change; you will not have to refocus your camera. This is due to the high tolerance and very low thickness of the substrate and coating.

Comparing Astronomik CCD Photographic Filters to our Visual Filters: Unlike Astronomik Visual Filters which do not require IR blocking, our Astronomik CCD Photographic Filters do include IR blocking filter layers to prevent any problems from Infrared Radiation (IR) when using CCD and chemical photographic devices.

Astronomik filters come with a 10 years warranty. 

Please note, the "unmounted" filters do have a black retaining ring, the protective ring and blackened filter edges prevents stray light, the filters are mechanically protected and easier to handle.
