Description

This Celestron variable polarising filter is ideal for when you want to selectively reduce the brightness of celestial objects. Unlike regular Moon Filters and Neutral Density Filters, the level of brightness can be varied 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 colour 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 Polarising 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 colour or neutral density, if needed.
