When you want to selectively reduce the brightness of celestial objects for a customized view, the Variable Polarizing Filter is the perfect choice. Unlike regular Moon Filters and Neutral Density Filters, the level of brightness can be reduced to just 1% or as much as 40%. To make the adjustment, simply rotate the filter’s lower ring and the image gets brighter or dimmer. This filter does not alter the color of the object you’re observing, making it a great choice for astroimaging, especially when imaging the surface of the Moon. By reducing the brightness, lunar details become more pronounced and defined. This filter can also be used to darken the blue-sky background when hunting for planets like Venus or Jupiter in the daylight, making the planet stand out from the background. The Variable Polarizing filter threads onto any SVBONY 1.25” eyepiece. Question:Mine don't reduce the light to anywhere remotely near 1%. Do yours? Answer:Per the description, this polarized filter offers "light reduction rate FROM 1% to 40%". It Does Not say that it reduces light "TO" 1%. to 40%. Those are two Very different statements.
