Celestron 1.25” UHC/LPR Light Pollution Filter
The Celestron UHC/LPR Light Pollution Reduction Filter - 1.25 in is 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).
The new ultra high contrast (UHC) LPR filter has improved contrast over the typical broadband filters. Sky background is darker, and contrast of emission nebulae are noticeably improved. The advanced 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 perfect filter for viewing nebula from light polluted skies, or for boosting the contrast of nebula from dark sky sites.
In addition to it's optimum spectral and optical characteristics, the UHC/LPR filter offers important features that set it apart and result in the highest quality celestial views:
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"-11" 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 60nm 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 (656nm).

Shipping costs are charged by either dead weight or cubic weight (whichever is greater).
Dead weight = The actual weight of the item. Cubic weight = L x W x H (Meters) x Cubic Conversion Rate (250).
Multiply the height x length x width = 0.35 x 0.65 x 0.4 = 0.091 m³ (Cubic Measurement)
To convert 0.091 m³ to a weight in kilograms: Multiply 0.091m3 x 250 (Cubic Conversion Rate) = 22.75 kg
