When I purchased a 13 inch Coulter dobsonian back in the 1980's, it had a product warning that "this telescope has a self destruct mechanism. If you point it at the Sun it will burn to destruction."
Very true, as anyone who has tried to point an unfiltered telescope of more than about 6 inches in apeture would find out. At the committee meeting of a local astronomy club one member volunteered that she pointed her 10 inch at the Sun (unfiltered) and it started to smoke. The experiment was aborted before the scope burst into flames.
