Light Pollution Filters
From catching your first glimpse of the Owl Nebula with your brand new 8" Dobsonian to adding critical data to a thirty-hour exposure, light pollution filters have certainly revolutionized this wonderful hobby! These observation accessories are designed to block different levels of light pollution while allowing the light from your favorite deep-sky target to shine through. Objects that, just a few decades ago, were known as “difficult objects” can now easily be seen with the right filter. Don't overlook this important accessory.
