UHC filters or light pollution reduction filters are designed to selectively reduce the transmission of certain wavelengths of light;especially those produced by artificial light
Sky background is darker;and contrast of emission nebulae are noticeably improved;the perfect filter for viewing nebula from light polluted skies;or for boosting the contrast of nebula from dark sky sites
Due to its ability to produce exceptionally sharp and clear images;this UHC filter is considered one of the most popular astronomy accessories;it can be used not only for celestial observations but also for astrophotography
Fits all standard 1.25" scope eyepieces;Its role is to reduces the focal length of your telescope by half ;increasing the field of view;and shorter exposure times for astrophotography;usually for a longer focal length telescope
