Shameless plug: I make time-lapse animations of solar flares (among other things) for fun, like this M-class [1] (46 min. of real time, 90 mm diameter telescope with narrow band Hydrogen-alpha filter).
Can you see anything if you look directly through the filter at the sun? I’m assuming it’s just a fuzzy red blob?
Yes, you can see just fine (with a bit less contrast than in those images). Of course, flares and prominences will not move in front of your eyes, but they do change over a few minutes.
Awesome! I always wondered about that.
Stunning stuff. The dark sunspot in the foreground and the one behind the tangle of plasma is intruiging.
