1.25" moon and skyglow filter is a multi band pass filter transmitting a high percentage of light in the visual spectrum;the filter enhances contrast when observing brighter objects including the moon and planets

Telescope eyepiece cutting light pollution;the filter has a mild effect of darkening the background of the night sky so that the fainter objects are more clearly seen contrasted against the blackness of space

The filter effectively filters out selective wavelengths of low pressure sodium and other man made sources typically used in street lighting;although it is not a nebula filter;it enhances the views of deep sky objects by increasing the contrast of these objects against the background sky

Premium Material: Aluminum frame, plastic thread and optical glass, durable and no damage to your lens

Transmits only 13 percent of the incoming light, boosting contrast and ability to discern detail on the Moon

Helps reducing overall brightness without altering color, so that not only will more surface features and details pop out, but also you can study them in greater comfort

Three neutral Density (ND) Filters with different levels of light transmission (13%, 25%, and 50%) allow you to choose the perfect filter for your viewing conditions

Moon & Sky glow filter provides high contrast views of the lunar surface and enhances observation of deep sky objects from light Polluted Skies

Aluminum filter cells provide a rigid, durable housing for the filter glass and are threaded on top and bottom for stacking

A must-have to safely observe without damaging your eyes - optical filter fits snugly over your telescope's aperture to block 99.9% of incoming light.
