Celestron 1.25" UHC/ LPR Light Pollution Telescope Filter

 

The Celestron Light Pollution Reduction (LPR) Filters are designed to selectively 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).

Reduce the Light Pollution in Your Images with the Celestron LPR Filters

  • The new ultra-high contrast (UHC) LPR astronomy filter has improved contrast over the typical broadband filters. Sky background is darker, and contrast of emission nebulae are noticeably improved.
  • Its modern technology coatings enable the filter to achieve an outstanding transmission of over 97% across the entire bandpass, with total blockage of prominent light pollution lines. 
  • The multi-layer dielectric coatings are plasma-assisted and Ionbeam hardened using the latest technology for durability and resistance to scratching. Improved transmission translates to maximum image brightness and contrast.
  • Users of smaller, 4-inch to 11-inch telescopes will especially appreciate the high efficiency, and larger scope users will love the rich star fields and detailed subtle nebular shadings that are left intact.
  • The high transmission, sharp cutoffs, and more moderate 60 nm passband of the UHC/LPR filter retains a more natural view, yet significantly boosts overall contrast. Imagers will appreciate the broader bandpass and inclusion of an extremely efficient H-Alpha passband (656 nm).

This narrowband filter is hard to beat at any price

This filter has a narrow notch at OIII and Hb and another one at Ha. With an eyepiece with a focal length of greater than 5.5 times the f-stop of your telescope you should be able to see the Veil Nebulae C33/34 under dark skies. Very nice.
