Celestron’s Moon Filter is an economical
eyepiece filter for reducing the brightness of the Moon and improving contrast,
so greater detail can be observed on the lunar surface. The clear aperture is
21mm and the transmission is about 18%. This makes the filter ideal for
virtually any aperture telescope making the view of the Moon far easier on the
eye and helping preserve dark adaption.
It is difficult to look at the Moon through a telescope and see all of the
details due to its brightness. When amateur astronomers observe the Moon, it is
beneficial to use a Moon Filter. A Celestron Moon Filter provides similar
benefits to those of sunglasses, our eye relaxes and opens up to let us see more
detail. This is especially important when observing the Moon when it is near
full.
The Celestron Moon Filter simply screws onto the insert barrel of most 1.25”
eyepieces. It only takes a second or two to transform your regular eyepiece into
one suited for lunar observations. A Moon Filter is also helpful when observing
Venus or bright terrestrial scenes.
