Product Description

PrimaLuceLab UHC 50.8mm Broadband Nebula Filter

The PrimaLuceLab UHC filter is used to block light pollution wavelengths from areas compromised by light pollution. This helps improve visibility of galaxies, nebulae, star clusters and other faint objects.

The UHC filter reduces light pollution mainly caused by sodium vapor lamps and mercury, dramatically improving the visibility of many faint objects such as galaxies, nebulae and star clusters. Only the most important lines of natural emissions pass through such as H-beta (486nm), OIII (501nm) and H-Alpha (656nm).

All PrimaLuceLab filters are tested to verify substrate and coating quality.

Technical Specifications:

  • Delete the most important frequencies of the light pollution
  • Improves the visibility of faint objects darkening the sky background
  • Anti-reflective multi-layer coating to not generate ghost images
  • Transmittance higher than 95%
  • Quality substrate not to introduce aberrations in the images
  • Available in 2 versions: 31.8mm (1.25") and 50.8mm (2") diameter

How to use the filters:

PrimaLuceLab filters are available in two diameters, both 31.8mm and 50.8mm which are common standards in telescopes and accessories. Depending on the photo adapter being used, they can work well with a CCD or DSLR camera as well as screwed to optical accessories like eyepieces and diagonals. Warning: 31.8mm filters do not work with 50.8mm diameter accessories and vice versa (unless there are special adapters). When you choose the version of your filter, be careful to choose the diameter compatible with your equipment.
