- Allows you to see features and details through a telescope that would normally be lost due to light pollution
- Blocks all forms of light pollution while passing critical hydrogen-beta and ionized oxygen wavelengths of light

- Use with any filter-thread equipped 1.25" Orion eyepiece. Metal filter cell construction.
The UltraBlock is a great filter for deep-sky observers located at highly light-polluted sites. Blocks all forms of light pollution - mercury vapor and sodium emission bands - while passing the critical hydrogen-beta and ionized oxygen wavelengths. With an UltraBlock, emission and planetary nebulas surface from the washed-out background sky. In dark skies, the UltraBlock also enhances the sky presence of a significant number of fainter deep-sky objects over unfiltered and wideband-filtered views.
