Celestron Variable Polarizer, 1.25"

The Celestron Variable Polarizing Filter lets you customize the brightness of celestial objects by adjusting light transmission from approximately 1% to 40%. Simply rotate the filter’s lower ring to make the image brighter or dimmer, giving you greater control than standard Moon or neutral density filters.

Enhanced Viewing and Astroimaging

Designed to preserve natural colors, this filter is ideal for lunar observations and astrophotography. By reducing glare, it helps reveal more detail on the Moon’s surface. It can also darken the blue-sky background during daytime observations, helping bright planets such as Venus and Jupiter stand out more clearly.

Easy Installation and Filter Compatibility

The filter threads onto compatible Celestron 1.25-inch eyepieces for quick and easy installation. Its threaded design on both sides also allows it to be combined with compatible color or neutral density filters for additional viewing flexibility.
