I think this started when I noted that the focal length of my refractor is the same as the fl of the reflector and hypothesised that eps that I found useful would also be useful for Rod. I never meant it to go any further.

No you don't need a filter. The limit of 200x applies to refractors because they suffer from chromatic aberration whereas a reflector doesn't. So the reflector should be capable of 50x per inch of aperture. However IMHO 300x is very high and you won't often use it. I think starting with a 200x ep is a good idea. See how you go after that. In general buy relatively few good eps and plan to keep them. I have three scopes but only one set of eps. I may sell a scope but I have no plans to part with any eps.
