What i'm thinking Dennis, is that the white light filter blocks the h-a wavelengths coming through, so putting a h-a EP filter in isn't going to help at all except to make the image red, as your avi shows.

I've never heard of the H-a EP filters (used mainly for deep-space imaging) used for solar imaging.
