Product Description

Product Description

This versatile filter acts like a dimmer switch for your telescope, toning down the brightness of the Moon or planets to a level that is comfortable. 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. Available in 1.25" and 2" sizes. Storage case included.

From the Manufacturer

The Orion Variable Polarizing eyepiece filter acts like a dimmer switch for your telescope, to tone down brightness and accentuate contrast of bright celestial objects. Gives you much finer control of the image brightness compared to a standard fixed-transmission telescope eyepiece filter for optimal performance. Adjust the amount of light transmission from 1% to 40% by rotating the eyepiece filter housing. Consists of two high-grade glass polarizing filters in an 1.25" rotating anodized aluminum cell. Threaded for use with any Orion 1.25" telescope eyepiece equipped with filter threads

I'm a novice astronomer and about 6 months ago purchased an Orion IntelliScope XT10 (great scope, see my review of it). I love looking at the moon but it's so excessively bright in this scope. I'm a big fan of Orion's products, and their service is the absolute best, so when looking to purchase a filter I decided to go for this one. It's only 2 pieces, very easy to assemble and attach to any 1.25" eyepiece. It's also great how you can vary the brightness from near maximum to very dark. Makes viewing the moon a WHOLE new experience. Brings out more detail and eliminates the eye pain. Once again, Orion has made a very satisfied customer out of me!

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.

When looking at the moon through a telescope larger than 6 inches or so, you need something to cut down on the excessively bright moon. This filter allows you to vary the amount of light coming through the eyepiece, and adjust it to a comfortable level. I'll never sell mine.

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

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.

I was surprised at how much of a variation this filter provides. Really tops my old moon filter.

The Orion Variable Polarizing Filter is perfect for when the moon is half and full! Gives accurate detail at any level. The only thing people need to understand is that adjustments need to be made before tightening the screw on your eyepiece. I recommend that when using keep your eyepiece loose until you have adjusted the polarizing lens to fit your needs. I often find myself changing the darkness until I find the perfect spot for my eyes. An easy piece to use and enjoy.

I decided to get this filter as opposed to the standard moon filter so that I had a bit more flexibility. At first I was a little discouraged by my purchase because it's not easy to adjust the level of light you are letting through on the fly. You have to take the lens out, adjust it, then put it back in. And you have to keep doing that until you find the desired setting. I would say that I am still happy with choosing this over the standard moon filter though.
