Product description:

The Omegon Light Pollution Filter is a type of broadband filter. Its effectiveness makes it universally applicable. The broad passband allows star clusters, galaxies, nebulae and comets to be better observed. However, it also filters out annoying artificial light such as street lighting.

Both the Omegon UHC and Omegon OIII filters are limited in their application to a few objects. The Omegon Light Pollution Filter is therefore more useful for generally increasing the contrast of faint objects, without filtering out the spectrum of possible observing targets.

The Omegon Light Pollution Filter is not only useful at light-polluted sites; the contrast is also increased at dark sky sites.

The advantages in a nutshell:

a first filter for those on a tight budget
very suitable for smaller telescopes
can also be used for astrophotography
stars are not as strongly coloured as with a narrowband filter

Omegon IR / UV blocking filter - keeps your planetary images sharp

Really sharp planetary images are only possible using an IR/UV blocking filter. This Omegon filter only allows the visible light between 400 and 780nm through. The UV and IR regions of the spectrum are completely blocked.

CCD exposures of planets and stars - sharp images

A CCD camera is not only sensitive to visible light but also to other wavelengths. Planets not only shine in visible light, but also in the infrared for example. But they are out of focus in the IR region. The Omegon filters only lets through the visible light, the light that is really 'wanted', meaning sharp planetary images.

Solar observing - blocking UV light

The Omegon UV/IR blocking filter is also very useful when observing the Sun. The harmful UV rays that can contribute to cataracts are filtered out. The filter is also essential when using a Herschel wedge, but is also extremely useful when observing using an objective solar filter (e.g. a foil filter).

Your eyes are valuable! - protect them with an Omegon UV/IR blocking filter.

The advantages in a nutshell:

only lets through visible light
blocks the UV and IR range
particularly useful for planetary imaging with webcams
optically polished and coated
continued in a robust 1.25" aluminium housing

Omegon deep sky broad-band filter - increase the contrast of deep sky objects

The Omegon deep sky filter boosts the contrast of deep sky objects. It can be used for both visual observing and astrophotography. The filter blocks artificial light sources, bringing nebulae back into view.

For visual observing and small telescopes

Have you ever looked at a photo of the Earth taken from space at night? A sea of artificial light extends over the continents. Street lamps, building lights and other artificial light sources can rival the light from astronomical objects available to astronomers.

Using a deep sky filter is the trick for seeing objects clearly, despite this light pollution. This broad-band filter is even suitable for smaller telescopes.

For urban astrophotography

Even comparatively short exposures will normally show an extremely bright sky under light-polluted city skies. But the deep sky filter lets you take the most beautiful exposures even here. You can extend your exposure time while still keeping a dark clear sky. You will have more contrast and the night sky will remain dark - and with your astronomical object clearly visible.

Keep the good, throw out the bad - there are good and bad wavelengths

The deep sky filter only passes the light which is important for observing. These are mainly the hydrogen lines at 486nm and 656nm and the doubly-ionized oxygen lines at 496nm and 501nm. Nebulae, for example the Orion nebula, only shine within these tiny regions of the spectrum.The light from mercury and sodium vapour lamps, the normal artificial light sources, are blocked.
