More About Telescope & Eyepiece Filters
By using a filter to selectively block and transmit portions of the visual spectrum, you will notice a huge difference in the amount of detail you're able to see in astronomical objects. Moon, solar, planetary, and light pollution filters from Orion Telescopes are image-enhancing staples that you will use almost every night out. And Orion carries a variety of more specialized narrow-band filters that will appeal to advanced observers and astrophotographers.
