Review on 🔍 Eisco Spectroscope with Advanced Direct Vision by David Plunkett

I would recommend smaller and cheaper gemstone spectroscopes. I thought it would be an upgrade but there are some issues: slit edges so so so much Grossly oddly enough, the vertical sides are flat. Still, that means you'll be drawing a lot of lines through your lens. It sucks...sometimes. Putting it anywhere will break the alignment - This could be a great tool for someone into be a developing country or something, it's made of a straw thread that holds the prism in place.
