Omegon Filters UHC Filter, 2"

The operation of a UHC filter is very simple. Filters sky brightness due to artificial light. Since many celestial objects, such as nebulae, radiate in other wavelengths, this can achieve a considerable increase in contrast. The background sky appears darker and faint details suddenly become visible. Observing first without and then with a UHC filter makes the presence of an object very obvious.

Using a UHC filter is not only useful on sites with light pollution; contrast is also increased at dark sky sites. Many objects only become visible for the first time when a UHC filter is used. But also, highlights like the Orion, Lagoon or Swan nebulae show a whole new side of them.

An Omegon UHC filter is one of the most useful accessories you can own and no eyepiece case should be without it. The Omegon UHC filter can be used with all 2” eyepieces.
