Home Filters Lunar & Planetary Filters Celestron Neutral Density Moon Filter 1.25 Inch
Reduces brightness and cuts glare, increasing clarity of the Moon, Venus, and bright double stars, the filter is glass with an aluminum cell that attaches to 1.25 inch eyepieces and is threaded on both sides so it can be stacked with colour filters. 13% light transmission Provides a true colour image Threads on to any Celestron 1.25 inch eyepiece or other brands with standard filter threads
The Neutral Density Moon Filter attaches to a 1.25 inch eyepiece to lower the amount of light entering the eyepiece by 87%. The Moon is one of the most viewed objects in the sky, but you shouldn’t be deprived of its features due to brightness. This filter only allows 13% of the telescope’s light to reach the eyepiece, making it a lot more comfortable to view. Unlike colour filters, the Neutral Density Moon filter affects all colours of the visible spectrum evenly, darkening the image without shifting the colour. Some Moon filters are #58 Green filters, and while they work well for cutting glare, they also add an unnatural green cast to the Moon’s surface. The Neutral Density Moon filter gives a true colour image. This filter is also great for helping to cut glare and increase contrast when viewing bright planets like Venus or Jupiter, or even to dim bright stars when splitting close double stars. The filter is glass with an aluminum cell that attaches to 1.25 inch eyepieces and is threaded on both sides so it can be stacked with colour filters.SpecificationsSize diameter 31.75mm (1.25")Cell Housing Aluminum cell housingStackable Filter YesLight Transmission 13%Dimensions Filter only 31mm x 11.5mm (1.22" x .45")Dimensions Case only 54.5mm x 43mm x 18mm (2.14" x 1.7" x .7")Dimensions Packaging 60mm x 50mm x 23mm (2.36" x 2" x .9")Weight Filter only .21 oz (6 g)Weight Case only .5 oz (14 g)Total Package Weight .88 oz (25 g)
Very pleased with this I can look at the Moon without discomfort. The screw thread is machined well, so it fits easily onto the telescope eyepiece. The filter also came in handy for holding behind the finderscope when I was aligning it in the daytime, so I could see the red rings against the background of white cloud.
