sensor
Steve Higgenbotham seems to be confusing *resolution* and sensitivity. I can *detect* visible light source *millions* of parsecs away with a "sensor array" that's less than 10 *centimeters* across. But I can't *resolve* it very well (my 3.5" refractor can detect Andromeda and other galaxyies quite well, but the detail *sucks*... :-) You need increased detector radius to increase *resolution*. Increasing radius with booms does *not* increase sensitivity *at all*.
