Product description:Omegon premium Moon filter - to ensure that your lunar observing is fun Does the Moon appear far too bright when observing it through your telescope? The Omegon Moon filter reduces the brightness and increases contrast. It screws easy into your eyepiece, permitting relaxed observing and stopping the Moon from dazzling you. The advantages in a nutshell:
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. From 200 mm aperture - only 13% light The Omegon Moon filter reduces the brightness of the Moon, allowing only 13% of its light into your eye. This makes it ideally suited for lunar observing with larger telescopes with a 200mm aperture or larger. 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. A Moon filter belongs in the eyepiece case of every amateur astronomer. But, above all, it is a must for comfortable lunar observing. Specifications:
