Description

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 Celestron 1.25" eyepiece. 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.

Henry O. ★★★★★

I was really struggling with glare on Jupiter until I tried this, the smooth rotation to adjust brightness made all the difference. It's surprisingly sturdy for such a small filter.

Madison T. ★★★★★

Finally, a filter that lets me dial in exactly how much light to cut instead of being stuck with one fixed density. The variable rotation ring is smooth and clicks nicely into place, which makes swapping between a bright gibbous moon and a dimmer star field effortless.

Eli R. ★★★★★

The ability to dial in just the right amount of dimming for Jupiter is fantastic—the ring detail really pops without washing out the planet. It threaded onto my 1.25" eyepiece smoothly and feels solidly built.
