Celestron Moon Filter

For more comfortable lunar viewing, the Celestron Moon Filter is a simple but worthwhile telescope accessory. This 1. 25-inch screw-on eyepiece filter reduces the Moon’s brightness and improves contrast, helping finer surface detail stand out more clearly when conditions are especially bright, particularly near full Moon.

It threads onto the insert barrel of most 1. 25-inch eyepieces in seconds, making it an easy addition to a regular observing setup. A clear aperture of 21mm and light transmission of around 18% give it a practical balance for bright lunar sessions. It is also useful for observing very bright planets and bright terrestrial scenes over sand or snow.
