Celestron 94107 Variable Polarizing Moon Filter - Reduces Brightness and Glare, Compatible with 1.25" Eyepieces and Suitable for Lunar, Venus & Double Star Observation, Black

Used it on our AZ70 scope and it cuts the glow of the moon down good. Works as should.

Worked great on my Celestron 130AZ's 10 and 20mm's. Brought out great detail.

Works great although it rotates very easily making it a little difficult to keep it right where you want it while putting the lense in.

With this I can finally point my telescope at the moon without worrying about burning my retinas good for reducing brightness does allow for more detail to show

Am very pleased with the lense.

You can tell a pretty large difference between the amount of light reaching your eye using this piece. The full moon is still to bright to edge in all those details but it will take away some eye strain. As far as using it for photography, you will have to adjust coloring to get out the green tint. If you use lightroom, adjusting the temp to -5 and the hue to 5 will give you a kind of natural bluish tint. As I stated before the full moon is still a light pollution monster so your camera may do it better justice adjusting the ISO or frame speed. Maybe ISO 80 and 1/125 fs. But if you're looking at a Waning Gibbous this filter will help manage the ambiance so you can see those craters hiding off to the edge in the shadows. Pretty good for it's price. It also fits in both my celestron eye pieces and pylossl which is nice. Can switch between my newtonian reflector and celestron refractor without to much eyepiece play. I don't recommend for stargazing or looking for planets unless you're using a high power piece

Meh it does its job, but there are much better options. Celstron provides NO specifications on how much light it actaully blocks. It also comes in sheap plastic bag that doesn't protect the lens at all. There are much better options from other brands.
