Haven't had the best viewing skies to try it out yet. What I did see, it seems decent. Makes a bit of sound like loose parts if you shake it. Seems to not disturb function, just speaks to quality.
Very high quality eyepiece. You can tell just by holding it, it's heavy because of the quality components. No more changing out the 4 eyepieces my telescope came with. And this unit has 5 different magnification levels so it's even more options. All we have to do is turn the. knob on this new eyepiece and we're at a different magnification level. Just takes a quick adjustment to the telescope's focus knobs and we're good to go. And the value is spot on. All decent telescopes should come with one of these. It makes things much easier when you're out in the dark looking at the wonders in the sky. Thank You!
