This very practical Red Dot Finder (r.d.f.) comes with a handy, quick-release T bracket included in the package. It fits perfectly on all William Optics telescopes.
With the Red Dot Finder, centering celestial objects on the sky has never been easier! Looking through the finder with one eye while leaving another open gives you a greater sense of orientation. There are four reticle patterns selected with a simple rotating dial and adjustable brightness to suit your observing environment.
The quick release base can also be purchased separately to use the same RDF on different telescopes without having to unscrew the base every time.
