Product Description

The Moon's disk, even at partial phases, is intensely bright with reflected sunlight. The glare washes out most of the craters, rilles, and other surface details from view. Our Moon Filter reduces the glare, allowing transmission of only 13% of the reflected light. Not only will you see more surface features, but you can study them in greater comfort. The filter reduces irradiation, which is the distortion at the boundary between light and dark areas, such as along the lunar terminator. The Orion Moon Filter is especially useful to owners of large-aperture scopes, in which the Moon's brightness can be overwhelming. It uniformly reduces light over the entire visible spectrum. Screws into threaded eyepiece barrel.

rated 5 out of 5 Excellent filter
by C. Matherne from South Louisiana, 2009-11-17


Makes viewing the moon much easier on the eyes. A definite for those interested in scanning the moon.



rated 4 out of 5 Helps when looking at the full moon
by Rock Elm Irv from Columbia, TN USA, 2009-09-12


Found this filter to be helpful when looking at a full moon with high magnification, but rarely used. Does what it should, but not sure it is really necessary.



rated 5 out of 5 A MUST if you want to look at the moon!
by M. Pulaski from Runnemede, NJ United States, 2009-03-04


Even in my light polluted area, looking at the crescent moon in my 8" dobs is almost painful on the eyes. I can only imagine that a full moon would be downright unbearable to view.

The filter screws in very quickly after removing it from its handy hard case. Once in place, the moon is a heck of a lot easier to look at. Also, when you are done looking, its a lot easier and quicker to adjust back to the night time darkness. I found that after looking at the moon without a filter, I couldn't see a thing outside in the night for about 30 seconds. This filter certainly helps with that.



rated 5 out of 5 It Depends . . . Why Do You Need It? What Scope Do You Use?
by R. Kirkham from Rushville, Illinois USA, 2009-01-10


The larger the aperture, the more light that is gathered. The moon is bright through my binoculars, but I don't need a filter. I've never used a filter in my 4.5". But my 4.5 isn't a very good scope. When I get up to my 6" I pull out the moon filter on nights when the moon is or is near full. I still do not need it most of the time. When the moon is full it makes all the difference in the world. Over 6" in aperture the filter becomes much more necessary.

So you must ask yourself, what scope are you using? How often do you want to study the full moon? For me it is worth the cost. It was so worth the cost it was the first filter I purchased. You will have to decide for yourself.



rated 5 out of 5 Does exactly what you expect it to do
by Tad J. Wesley from Terre Haute, IN United States, 2008-07-29


If you've dealt with Orion in the past, you expect quality optics, that are functional without being terribly overpriced. Such is the case with their moon filter as well.

You don't need this filter on smaller phases of the moon, but as the moon approaches full, and gets increasingly brighter, adding this filter will greatly enhance the views by taking the edge off the glare so the details are clearer.
