You'll have to go direct to the American supplier now I beleive. It is great stuff though. Also used it my Carton 100mm f/13.

Ok.............this was a 2011 thread and in 2014 there was some disgruntled users on Cloudy Nights about the way ProtoStar operate.
Its sad things turn out this way, but that  flockboard seems such an easy install, fold it and pop it in the OTA, replace the focuser, and  a few minutes to re-attach my end-pieces, job done?
