Product Highlights
  • Reduces Transmission of Wavelengths of Artifically-Produced Light

LPR (light pollution reduction) filters are designed to selectively reduce transmission of certain wavelengths of light, specifically those produced by artificial light.  These include mercury vapor, high & low pressure sodium vapor lights and the unwanted natural light caused by neutral oxygen emissions in our atmosphere.  The UHC LPR filter has improved contrast over the typical broadband filters, giving darker background skies and noticeably improved contrast of emission nebulae.  The advanced coatings enable and impressive 97% total transmission across the entire bandpass, with total blockage of prominent light pollution lines.  It is a perfect filter for viewing nebula from light polluted skies as well as for boosting the contrast of nebula from dark sky sites.

Multilayer, plasma-assisted and Ionbeam hardened dielectric coatings yield supreme durability

          Caveat emptor! Useless piece of glass!

                Comments about Celestron UHC (Ultra High Contrast) Light Pollution Reduction 48mm Filter (Fits 2" Eyepieces):

                Bought this product for my Celestron CPC 925 with 31mm Luminos eyepiece. I thought it will make all the difference in my backyard viewing of DSOs (as is represented by the product's description) in a fairly light polluted area about an hour drive from NYC. Results have been consistently disappointing. My eyepiece is better off without it! This UHC (Ultra High Contrast) LPR should be renamed Ultra "Hype" Contrast. Very disappointed!

                  I have a Celestron CPC 1100 telescope. I live in fairly rural area (no street lights), however there is still 'skyglow' from neighbors, etc. I screw this filter onto my 2 inch eyepiece, and it increases the contrast for those dim nebulae, etc. I tried viewing Jupiter with it, but it caused discoloration (this was expected).

                  I was expecting a wow experience but the detail in Nebula from a moderatly light poluted sky was not that much better than my existing narrowband filter.
