2" Telescope Moon Filter, Moon Filter for Telescope, 2inch Eyepiece Accessory, Great for Full Moon Observing

• 2" standard size for Celestron, Orion, Sky-watcher, Meade, William and any brands models.
• 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.
• It is an eyepiece filter for reducing the brightness of the moon and planets and improving contrast.
• 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.
• Standard filter threads on both sides. So you can mount other filters together when using this filter
