The continuum filter only enhances the visible features - surface granulations, umbra/ penumbra etc.
When you say you have a "replacement Ha filter" fitted - what do you mean?
The normal replacement is just a UV-IR blocker.
The Baader Solar film has a slight IR leakage which doesn't affect visual but can give some loss of contrast with non= IR blocked CCDs.
Hope this helps.
