Our Moon is the most popular object to observe with a telescope. It is an obvious object, easy to find and full of interesting geographical features to explore.

Moon filters enhance viewing of the Moon by reducing the Moon's bright glare, improve contrast and make faint details easier to see. Amateur astronomers call Kuusuotims "Sunglasses of the Moon" because they provide a more comfortable view and reduce eye fatigue.

This Moon Filter Set contains all the filters you need to observe the Moon during its various phases. The set enables choosing the best possible filter for different eyepiece and telescope combinations. Use the darkest filter with large-aperture telescopes and low-power eyepieces. Use lighter filters with smaller telescopes and stronger eyepieces. This kit is essential for those looking to take the next step in exploring their telescope's Moon viewing capabilities, or for experienced Moon watchers who use a variety of telescopes and eyepieces to observe the Moon.

In this package you get:.

Three neutral density (ND) filters: ND96-0.9 13% T, ND96-0.6 25% T, and ND96-0.3 50% T —These filters dim the entire visual spectrum between 400-700 nm. ND96-0.9 filter transmits 13% of incoming light, ND96-0.6 transmits 25% and ND96-0.3 transmits 50%.

They do not give color to the Moon, but reduce the Moon's brightness. With the help of several ND filters, you can find just the right level of light transmission for the Moon, depending on its phase, the aperture of the telescope and the magnification of the eyepiece. ND filters can also be used to reduce the glare of Venus to better see its crescent phases and to help dim bright daytime views when the telescope is used to observe terrestrial objects.

Moon & Sky Glow Filter - This filter selectively reduces light transmission at different wavelengths and greatly improves contrast to observe subtle features of the Moon. This filter gives a very light purple color to the Moon. For those in light-polluted areas, the Moon & Sky Glow filter offers some contrast enhancement when viewing deep-sky objects, as the filter blocks some wavelengths associated with common forms of light pollution, e.g. low-pressure sodium (LPS) street lights.
