In case anyone is wondering, Brent is not kidding about gold mirrors. A few years ago Bruce Grim was having trouble with his mirror holding on to its coatings (the mirror had accidentally been impregnated by oil during fabrication). So after several failed aluminum coatings he had John strip the mirror down and apply a gold coating. Held up longer than aluminum, views through the scope looked the same and IR photometry was enhanced. And talk about pretty. Looked great (almost as good a Celestron orange <g>). BTW, eventually the gold came off too so Bruce finally fixed the problem for good by having John again strip the mirror and then apply a chrome coat and an aluminum coat over that. Patrick
