1.25" Orion 13% Transmission Moon Filter - Fits 1.25 Inch Telescope Eyepiece - Neutral Color for Lunar Detail and Surface Features

I'm an old school visual telescope user. I don't take fancy CCD images, I just like to point the scope at my favorites and let the photons actually hit my eyes. Sorta left the hobby for a while but recently dusted off my old 90mm refractor. Lost my lunar filter so I bought this one. The evening it arrived we had a prefect waxing gibbous. Thrilling results! Tamps down the light just enough while not affecting the colors. I also own some Orion 10x50 binoculars. They make good stuff.

An absolutely essential accessory for viewing the moon - even for beginners. I had been a (very) casual stargazer for years and never used any filter, but I decided to give this a shot when I upgraded telescopes recently. I had assumed it would just make the image fuzzier - but I was very wrong. Image clarity remains excellent, but it saves your eyes from the glare and allows you to observe far more detail. Really great product. I switched eyepieces and tried to observe the moon without the filter, but I couldn’t do it. It was far too bright for comfortable viewing. Great quality - it threaded into my eyepieces smoothly and with no problem. Feels well-made. Delivered quickly too. If you’re wondering whether or not you really need this product — you do. Might even be worth getting a couple of these to avoid the minor hassle of switching between commonly used eyepieces.

This does what it's supposed to: reduce the amount of light you get from observing the moon, and let me tell you it does work great. Not only makes it easier for the eye to observe the moon when most of its surface is illuminated, but also keeps the natural color of the image so the moon will remain white but just less bright. It also fits my eyepices perfectly. I would totally recommend this to anyone who wants observe the moon with a telescope, it's just more enjoyable for the eye than doing it without the filter.

This does make it easier on the eyes but for me this was a little too dark. I would have preferred 25% light transmission. Honestly I cant say the detail was better, I personally could see more without this however using stock lens it takes 30 seconds to adjust back to night vision where as with this its much faster. Reasonable price for this and it works perfect with my lens.

I'm new to astrometry and beside my scope, this is the first accessory purchase and I'm very pleased with it. It seems like a simple thing but just as sunglasses can bring out more details when viewing things, this filter lets me seen the moon much more clearly by blocking some of the glare. It sharpens the details, giving just the right amount of contrast so I can see the mountains and valleys much better now. Definitely worth the price for the improvement in viewing.

There are other filters that are cheaper but you do get what you pay for. Orion is a quality brand that has been in the game a while so spend the little extra money and get better filters.

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.

A very good moon filter thank you.
