Question Can you use an H-alpha filter behind a Baader solar film filter?
I think the topic asks it all.

I have a standard solar film filter - the 99.9999% sort of thing - so I just get white light images.

Now you have reduced the light intensity to something the CCD can cope with, can you then use a H-alpha filter to get narrow band?
