The reduction in brightness and glare unmasks detail in your viewing subject and greatly improves contrast. The filter consists of two high-grade glass polarizing filters in a rotating cell that allows you to adjust the amount of light transmission from 1% to 40%. Such control is highly desirable for lunar observing because the Moon's brightness varies with its phase. The filter is great for terrestrial observing too, especially on sunny days. The filter has an anodized aluminum cell, which threads into the barrel of any standard eyepiece. Now available in 1.25" and 2" sizes. Storage case included. | | | Features: | |

I like the way that you can make it as light or as dark as you want.

Amazing filter poor workmanshipMay 04, 2010
This is really a cool filter, you don't have to buy more then one, for each fase of the moon or to separete stars, this is the only one that you need.
You don't even have to remove it of the eyepiece to ajust, just turn the eyepiece, until you find the right level for you.
The only problem that I had, was that in the manufacturing montage, the work was poor. The top glass came lose, the rubber ring that holds it was badly placed, and when I thurned the filter that was somethin grinding inside of it.
But the guys in my astronomy club put the thing apart, cleaned it up, put it together again and now is working the way was supposed to: Amazingly

 Good and badMar 31, 2009
First, the good. If you think you want a moon filter and you're trying to decide between this and a neutral density filter, stop wondering and get this one. The adjustability is well worth the extra bucks. It really does work as advertized. At max transmission (40%) it is like you suddenly chopped your aperture by a third. At minimum transmission (1%), have fun trying to find anything other than the full moon. The biggest downside I can see here is that some moron will probably try to use it as a solar filter and burn an eye out.
Now, the bad. I was sure as I could be, ahead of time, that I wanted one of these things. In terms of time spent, the moon is my favorite observing target and I do a fair amount of digiscoping (or afocal projection photography, if you prefer) of the moon. Between first quarter and last quarter it is a punishing sight even in my modest six inch telescope. Near full, it's just flat painful. So obviously I need a moon filter, right?
I'm not so sure anymore. The filter does knock the light down to acceptable levels, that's true. But in doing so it knocks down the contrast, too, to levels that I find aesthetically yucky by eye or CCD. After a few weeks this thing landed in an out-of-the-way pocket of my eyepiece case and hasn't been heard from since. Turns out I prefer a brilliant, if painfully bright, moon, to one that is acceptably dim but unacceptably dull. Your mileage may vary.

Quality filter for the priceNov 18, 2007
Comes in two pieces that the user threads together prior to threading onto the EP. Easy to use. Priced appropriately for the quality. A must have for lunar and planetary observation.
