Sharpen your focus and enjoy more detail with the Light Pollution Reduction (LPR) filter. The eyepiece filter is specifically designed to reduce the transmission of certain wavelengths of light, specifically those produced by artificial light. This includes mercury vapor, and both high and low pressure sodium vapor lights and the unwanted natural light caused by neutral oxygen emission in our atmosphere (i.e. sky glow).
The advanced coating on the LPR filter makes the sky background appear darker, allowing colours to appear more vivid. Improved transmission translates to maximum image brightness and contrast. This is the perfect filter for viewing nebula from light polluted skies, or for boosting the contrast of nebula from dark sky sites.
The multi-layer dielectric coatings use the latest technology to make sure the filter is plasma assisted and Ionbeam hardened. This ensures durability and resistance to scratching.
