Product description

An ocean of city lights causes a large amount of background illumination that drastically reduces the visibility of space objects. This is the case everywhere but in the most remote rural areas. As a result of this you can see much less of an objects and much fewer objects than would be possible with your telescope.

With the NightSky UHC Filter this light pollution is almost completely blocked, strongly improving contrast for astronomical observations!

Under typical observing conditions only a couple of dozen objects are easily visible, even in large telescopes. Even in very rural areas in Europe there is still a certain amount of light pollution, reducing visibility of fine details.

The NightSky UHC Filter moves hundreds of additional objects within reach of your telescope! At the same time is strongly improves visibility of details.

The filter works with the following telescopes:

You can use the filter with any telescope that can use 2" eyepieces. Many 2"-1.25" adapters have an integrated filter thread. With such an adapter you can use this filter also in combination with 1.25" eyepieces. The filter will work well with any telescope from 70mm aperture.

How the UHC Filter works:

The light pollution caused by city lights is present nearly constantly throughout the entire visible spectrum. By contrast, many bright space objects emit light only in a few specific wavelengths. The most important of these wavelengths for visual observing are O-III and H-Beta.

Many objects emit light almost exclusively in these wavelengths.

This is where the NightSky UHC Filter comes in: It permits precisely these important wavelengths and at the same time blocks the other wavelengths nearly completely. This reduces the background light to a fraction of its original intensity, while the light from the object can pass almost unhindered. The result: A massively improved contrast!

The NightSky UHC Filter can be used to maximum effect on Gas Nebulae and Planetary Nebulae.
