Sehr leicht zu handhaben, eine Skala am Rand wäre jedoch hilfreich!

Like it
At low, medium and high polarizing settings it does not appear to harm the clarity of the view. Just does its job of reducing light. Very happy with it for the price.

Works Great and Replaces an Entire Set of Fixed Polarizing Filters
I'm very impressed with this SVBONY variable polarizing filter. When I got into astronomy decades ago, I needed an entire set of fixed polarizing filters for different uses and conditions. This filter has become my "one size fits all" polarizing filter solution! It's not only great for 'dimming down' the very bright moon (of course) but works great for bright planets like Jupiter and for solar astronomy -- when using an over the aperture optical grade solar filter. I particularly enjoy solar astronomy and this variable filter not only helps bring out planetary features like the bands of Jupiter but features of the sun like sunspots and faculae. It also works very well when using an eyepiece projection into a camera (or even a smartphone, like I use). Important: NEVER use a camera or look at the sun through a telescope without using an optically rated, over-the-aperture solar filter (as shown in my photos). Yes, it' is somewhat inconvenient to remove the eyepiece in order to make adjustments, but it's not nearly as inconvenient as removing the eyepiece, unscrewing a filter of a specific percentage, screwing in a different fixed percentage filter, then putting the eyepiece back in … only to do it all again if the fixed percentage filter you choose was still not right for the application. The range of percentages on this SVBONY variable polarizing filter is great, the filter's optical quality seems excellent and it's adjustment is very smooth. This is my first SVBONY product purchase, but certainly not the last.
