This is a high quality barlow lense. When used with your telescope and normal eyepiece you get a trippling of magnification. Most useful for EP's 24mm and larger. A 30mm EP becomes a 10mm with use of the barlow. The look and feel of the barlow are both high quality. Make sure you have a sturdy mount for the scope, owing to the increased weight.
I use this zoom eyepiece in my Meade ETX 80 and my Orion XT8i. It has become my default eyepiece. It is not quite as sharp and clear as my Meade or Orion Plossil eyepieces but it is fine for most cases. If I want to spend detailed time on a subject then I might use this to find the best mag then switch to a single mag. But may times this is the only eyepiece I use, sometimes combined with a 2X barlow.
Handy little tool, it works great. I'd give it 5 stars if the tip were a bit smaller. The higher powered, smaller mm lens were smaller than the cleaning tip and had to use the edge to clean. It is much easier to clean the lens of an eyepiece with this tool than a microfiber cloth alone. For me a 15mm and larger was a great cleaning tool. If you're careful with your eyepieces, the brush end is really all you'll use, but if you happen to get a finger print or other smudge on the eyepiece lens, this tool will sure render it spotless and clear again.
I'm pretty impressed with this little finder. It's simple to calibrate, fits the mount on my Galileo telescope (because they're the exact same telescope) and it's got some nice features. Two brightness levels is handy, especially when you're trying to view smaller objects. You can turn down the brightness and go. Now, I've seen complaints that the dot is large, which is true if you sit at the rear of your telescope. I prefer to look down the sight while I'm close to the focuser. The dot's much smaller and gives you much better accuracy. The build seems reasonably solid for something made completely out of plastic and it mounts nice and tight on the telescope. Overall, I'm very pleased.
