Hey Sun Dog,     Remember those properly filtered solar glasses ???  I draped the lens of one in front of my camera lens and got this composite result: http://ceastronomy.org/gallery/main.php?g2_itemId=2588  I know it isn’t H-Alpha, but it was an interesting experiment.

Since  your instrument is bigger than mine (i.e. C-14 vs Panasonic DMC-FZ18 , does that qualify me as a Sun Pup?
