Eliminate the natural sky glow and unnecessary transmissions produced artificial lights with the Celestron UHC/LPR Filter. Designed to improve the colour contrast, this filter helps see a sharp and clear view of the celestial objects. Its advanced coatings provide high light transmission across the visual spectrum, while the dielectric coatings resist scratches and quick wear and tear.

Celestron UHC / LPR Filter - 1.25 Inch Key Features:

  • 1.25” (3 cm) filter for selective reduction of light transmission, especially emitted by artificial lights
  • Ideal to view nebula, regardless of the sky’s pollution level
  • Use with large telescopes for detailed observations and nebular shadings
  • Ideal for small telescopes for enhanced brightness and contrast
  • Improved contrast for better visibility of the dark-sky objects
  • Advanced technology coatings for over 97% transmission across the spectrum
  • Ion beam hardened, plasma-assisted dielectric coatings assure scratch resistance & durability

  • FAQs:

    What kind of light transmissions can be reduced using the filter?

    The filter is used to reduce specific light transmissions, such as sodium vapor lights and mercury vapor. The atmosphere emits neutral oxygen, causing unwanted natural light (sky glow,which can also be reduced using the filter.

    Which telescopes can be attached with the Celestron filter?

    This UHC-LPR filter is compatible with various Celestron telescopes, including the equatorial 925 HD, computerised, NexStar evolution, and refractors.

    What is the purpose of multi-layer dielectric coatings?

    This filter has multiple dielectric coatings that have ion beam hardening and plasma assistance. They keep the optical elements safe from scratches and everyday wear and tear.

    Is this UHC-LPR filter better than the typical broadband filter?

    This Celestron filter provides higher colour contrast as compared to a typical broadband filter, making it a trusted choice of astronomers. It helps in darkening the background of the sky and improving the nebulae’s contrast.
