RD Red Dot Finder
You get what you pay for. That said, this finder is good value for its low cost. I mounted mine on my William Optics RedCat 51. The lightweight ABS plastic construction allows it to flex easily and deflect with large ambient temperature changes, and you need a light touch when tightening the screws on your dovetail mount. The lateral and vertical adjustment knobs more too easily; I've thrown my alignment off a few times reaching for the power switch in the dark and touching the wrong knob. On the plus side, the variable brightness dot works a charm and the finder puts me in the neighbourhood of my target on my first attempt every time. This is a good entry-level finder for scopes with a wide FOV.
