Don’t work at all. Using anything from a 10mm-40mm we have clear sight. Install this with any rey piece and it goes black. Can’t see anything no matter what you do. Works good as a monocular. That’s about it. Don’t waste your money.

You need Barlows this good. This really improves the image quality, colors look more natural. You lose a bit of light, but you gain much more. Glad I bought this. The single element Barlows are junk in comparison. You need this if you are trying to get the most out of your telescope.
