Celestron Neutral Density Moon Filter 1.25 Inch

Further details

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.

Reviews

  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.  (19/02/2021) KD - Oxfordshire
