Celestron – Moon Filter Kit – Fits 1.25' Telescope Eyepieces – Includes 4 Neutral Density and Sky Glow Filters Plus Lunar Map – Perfect Accessory for Astronomy Beginners

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.

I thought it would have a gray hue based on the picture. Not sure if i read description completely. Quality is fine.

Works nicely, eases viewing of the moon.Only drawback is that it is placed inside the telescope so changing the polarization requires disassembly of the eyepiece. In addition - if the telescope remains assembled - you may forget the filter inside --> might take time to understand why deep sky objects are not visible - but this was my fault, not the filter...

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

This filter removes glare while observing the moon in all phases. Detail really jumps out using this filter. Reasonably priced too.

I like how how you can quickly adjust the filter strength. It does unscrew in to 2 halves, so you can 1/2 on a barlow and the half on the eye piece. The quality is good, smooth adjustment it doesn't feel gritty. The threads are well machined and we'll built.

The outer diameter of this filter is smaller that the 1-1/4" barrel so that a lens cap fits too loosely to stay on. I am replacing this filter due to that inconvenience.
