WHILE USING A SAFE SOLAR FILTER, can you also use a H-alpha filter to get cool views and images of the swirling surface? I was looking at this H-alpha filter from Astronomik, and it says "The Astronomik 6nm H-Alpha filter may NOT be used for solar observation." Do they mean that using this filter alone without a proper solar filter will not keep you from burning a whole in your face? Or do they mean that it won't work at all for solar viewing.

It wont work at all - you won't get anything like you would get in much narrower solar H-alpha scope.

What Piotr said. You need a special filter (Etalon) to see the very narrow band of the hydrogen-alpha spectrum needed to see any details on the sun.

One from Lunt:

Or a Coronado Solarmax series telescope:

Or a Daystar solar filter:

There are others, but these are probably the most common.
