This premium Moon filter will reduce the unwanted glare from the Moon, maintaining your viewing comfort without loss of resolution. With 25% light transmission this version will suit any astronomical telescope equipped with a 1.25" focuser.
The Neutral Density Moon Filter attaches to a 1.25” eyepiece to lower the amount of light entering the eyepiece by 87%. The Moon is one of the most viewed objects in the sky, but you shouldn’t be deprived of its features due to brightness.
These high quality anodized aluminium, optical glass variable polarising filters reduce the amount of light entering your eyepiece. You can progressively dim the view when observing a bright object, such as the Moon or certain planets
This 1.25in filter consists of two joined polarized filters that provide continuously from about 2% to 40% as the rotating filter is adjusted. Great for lunar viewing without ruining your dark adaptation from staring at a bright image.
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%.
