There's no such animal as a "low cost solar prominance filter", Rob. If you're seeing prominences at all, then it is most definitely a hydrogen alpha filter, none of which are cheap.
As others have said, this sounds like a case of failure to tune the filter correctly or (heaven forbid), lack of the requisite blocking filter.
