Hello Gordon and everyone on this thread. This discussion got me thinking about a 6" reflector that my uncle still owns today. It was a kit scope from a Telescope Shop in Sydney don't remember the name but it's about 35 years old. Anyway I found this photo of a Unitron surfing at Barry Carter's site thought you might be interested.
