This versatile filter adjusts the brightness of visual images to an optimal level. It’s ideal for toning down lunar glare to a comfortable brightness, depending on the Moon’s phase and the magnification used. You’ll see more detail in bright views of the Moon or a planet, or in the Airy disk of a bright star, while barely altering the object’s color.
The filter consists of two polarizing layers mounted in a special cell, which when rotated varies the light transmission from 3% to 40%. Threads into 1.25" eyepieces or diagonals. Essential for regular observers of the Moon
