Adjustable Brightness Control For Your Telescope. Variable polarizing filter acts like a dimmer switch for your telescope, to tone down brightness. Reduced brightness and glare unmasks detail in your viewing subject and greatly improves contrast. Adjust the amount of light transmission from 1% to 40%. The filter has an anodized aluminum cell, which threads into the barrel of any standard eyepiece.
