William Optics Red Dot Finder M-RDF

This is one of the best red dot sights I've ever used besides Televues Starbeam. It's all metal, very solid, and the reticle a can be changed! It can project a teeny tiny dot, a circle with a dot in the center, regular crosshair, and a crosshair with a hollow circle so stars can be seen. The lowest illumination level is quite dim. The brightest level gives me blind spots. It will work in broad daylight with the sun out. The sight itself comes from a manufactur that produces these for guns. It explains the highest brightness setting. The finder comes with a rubber cover that can be put on so when you bring it inside--it won't fog up. The adjustments require use of an Allen wrench (included) which is annoying because I like to use thumb screws. Now that it is aligned I'll likely never bump it off again. It's still aligned just fine. It is everything I could ask for in a quality sight. The only real quibble I have over this is on cold nights--if I'm not careful and exhale near the sight, it fogs up instantly. A small heat strip fixes that though. I use this on my small go-scope. If I didn't already have a Starbeam on my large refractor I would buy another of these for it.

Very good as described
