About this product
Part Number: AD083
Astro Essentials Moon Filter 1.25" ND 0.3
Reduces unwanted glare when observing the Moon and planets.
This neutral density filter allows 50% of visible light to pass through, so only half the light entering the telescope passes through into the eyepiece, making the image 2x fainter.
Premium optical glass with anti-reflection coatings and a neutral density (doesn't affect colour).
Screws into the standard 1.25" filter thread of eyepieces and accessories. It can also be stacked with other filters.
See our handy guide to colour filters and how they can help improve your lunar and planetary visual observing.
