[Cel] A bright idea?

The website I got a lot of heliograph information from is:

http://myweb.cableone.net/kd7aoi/

 From the pictures of the American Service heliograph and the British 
Mance heliograph, it seems pretty clear that the mirrors are in fact 
flat. There's also a reference under one of the subsidiary links to the 
American heliograph, 4in mirror, being bright enough to hurt the naked 
eye at forty miles away.

Another website,

http://www.dself.dsl.pipex.com/MUSEUM/COMMS/heliograph/heliograph.htm

suggests that the maximum distance over which a heliograph flash can be 
seen with the naked eye is thirty miles.
