No, not really, Ken. I sold my PST a while ago, but I presume you mean I could use the SM40 etalon?
ATM my heads been in the realm of using my ED80 with the Ha filter so it works as a solar scope, widefield and guide scope without changing scopes on the mount. However, if I really settle down into solar and spectroscopy with the L200, then I suppose I could mount a dedicated solar scope in place of the ED80.
