HeUHC filterworks effectively and simply.Deletetheartificial lighting of the sky . Because many astronomical objects, such as nebulae e.g. e.g., they shine at a different wavelength,increasesnotablythe contrast . The background is rendered darker, the details appear. If you combine observation with and without a UHC filter, you will get a broad impression of the object. But we recommend the use ofUHC filternot only in regions of high light pollution. Under dark skies it also increases contrast. Many objects are only discovered if you use the UHC filter. But also some protagonists likeOrion Nebula ,Lagoon NebulaeitherCygnuswill show a facecompletely different.
