Visual Astronomy Filters

All-Star Telescope has a great selection of filters for visual astronomy.  These filters all have different purposes, and can cut down on the effects of light pollution, add contrast and detail to the planets and moon, and can even enhance the nebulosity of deep sky objects.  Filters screw into the threaded bottom of your telescope eyepiece and upgrade your view.  These can also make great gifts for the astronomer in your life.
