The Moon is too bright - tone it down a bit
The Moon can be so bright that you can easily read a newspaper by its light at night. But anyone looking through a telescope will note just how bright the Moon really is. It often irritates the retina and dazzles the eye in unpleasantly. No wonder - the full Moon is 25,000 times brighter than the brightest star in the night sky. So having a neutral density filter is definitely an 'ace up your sleeve' when observing the brighter lunar phases.
 
Filter with 25% light transmission
This filter is ideal for smaller and medium-sized telescopes up to a diameter of 150mm. The 25% light transmission reduces the brightness of the moonlight, allowing you to observe the Moon at any time - in comfort and without glare.
 
Polished glass for a clear view
You are purchasing a first class product with the Omegon Moon filter - a polished glass filter held in an anodised aluminium mount. The filter glass has been ground and stained throughout the entire glass volume. This avoidance of using a superficial coating means that it cannot wear out, even after many years of use.
