The Earths Moon is the most popular object to observe with a telescope. It is an obvious target that is easy to locate and full of exciting geographical features to explore. The Celestron Neutral Density Filter improves lunar vision by reducing the Moons light glare by 87%, for better contrast and dimly visible details that are easier to observe. Most amateur astronomers keep a lunar filter handy as an essential part of their observation kit, as it provides a more comfortable view and reduces eye strain. This filter does not change the color of the object you are observing, making it a great choice for astrophotography, especially for taking pictures of the surface of the Moon. However, a neutral density filter is not reserved for the Moon; it also increases contrasts when viewing deep sky objects in areas polluted by light. And for ground observers, this filter reduces brightness when viewing land targets surrounded by sand and snow. The Celestron Neutral Density Filter simply screws onto the insertion body of most 1.25" eyepieces and can stack with other 1.25" filters.
