Aluminum composite reportedly stronger, lighter than carbon
"Fred the Red Shirt" wrote in message oups.com... While it is not a technologically daunting task, it is not cheap for larger mirrors especially when you consider shipping. I have a 17.5" mirror that will need realuminizing when I finally get around to putting it into a scope. It has been cleaned exactly once, but the coating is nearly gone entirely after 30 years in storage. Offhand, do you know anyone who recoats mirrors that size? -- FF Maybe these guys: http://www.newportglass.com/nigcap.htm http://www.johndobson.org/links.html
