Astromania IR / UV blocking filter - keeps your planetary images sharp

Really sharp planetary images are only possible using an IR/UV blocking filter. This Astromania filter only allows the visible light between 400 and 680nm through. The UV and IR regions of the spectrum are completely blocked.

CCD exposures of planets and stars - sharp images

A CCD camera is not only sensitive to visible light but also to other wavelengths. Planets not only shine in visible light, but also in the infrared for example. But they are out of focus in the IR region. The Astromania filters only lets through the visible light, the light that is really 'wanted', meaning sharp planetary images.

Solar observing - blocking UV light

The Astromania UV/IR blocking filter is also very useful when observing the Sun. The harmful UV rays that can contribute to cataracts are filtered out. The filter is also essential when using a Herschel wedge, but is also extremely useful when observing using an objective solar filter (e.g. a foil filter).

Your eyes are valuable! - protect them with an Astromania UV/IR blocking filter.

The advantages in a nutshell:

only lets through visible light
blocks the UV and IR range
particularly useful for planetary imaging with webcams
optically polished and coated
