Astromania 1.25" IR/UV Blocking Filter - Keeps Your Planetary Images Sharp

Astromania 1.25" 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
• SHARP IMAGES: A CCD camera is not only sensitive to visible light but to other wavelengths; planets are out of focus in the IR region; the Astromania filters only lets through the visible light; meaning sharp planetary images
• Blocking UV light: The harmful UV rays that can contribute to cataracts are filtered out; the filter is also essential when using a Herschel wedge
• 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; continued in a robust 1.25inch aluminium housing
• This is a very high quality filter that allows you to view more clearly

This kind of Filters are made from renowned Schott and Hoya optical glass and allow for maximum contrast on viewing planetary and lunar detail. Individually precision ground, highly polished with maximum light transmission coatings on both sides, these filters are 100% guaranteed for life.
