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 filters lower ring and the image gets brighter or dimmer.
This filter does not alter the color of the object youre 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 1.25 inch eyepiece with a filter thread. Lastly, the filter can be threaded on both sides so you can stack it with other filters, such as color or neutral density, if needed.
