Hi everyone. I'm after some suggestions on how to deal with this monstrosity (ideas not involving vandalism preferred

). The new house that has just been built on the other side of my back fence has this ridiculously bright floodlight mounted ridiculously high up. The only places that need lights this high and this bright are shopping centre car parks and prison yards. It basically lights up my backyard as well. That is my observatory roof in the foreground.

Anyway, I was thinking of constructing some poles with black cloth that I can put up while imaging, to shade the light, but I also suspect it will contribute to the light glow in general. Would some kind of light pollution filter help at all with this problem? I am assuming that it is an LED floodlight.
