I'm after a glass solar filter to suit an Orion ST80 refractor (100.2mm OD tube). Would consider non-exact other sizes as I could machine an adaptor. I'm doing a daytime astronomy demo for a school holiday program.
I'd also be interested in a cheap/poor condition Coronado PST as long as the critical bits are working :)
Thanks Doug
