Captured with a 180 mm diameter telescope. The animation spans 20 minutes, with 20-second intervals between frames.

The closest I've gotten is being a little hacker and written a wget script to download from SOHO, but I feel like that's cheating compared to you ;-)
...but beware the unrelenting "I need bigger aperture and to travel to better-seeing locations".
that's one of the compelling reasons to get into solar observations. if we ever get to a point of worrying about light pollution blocking our view of the sun...
my current astro rig is specific for deep sky objects, and is a very wide angle telescope. when i observe the moon, maybe 50% of the FOV is the moon, so i want a different scope for viewing solar system objects that I can then attach said solar filters.

Your question got me curious, those are called penumbral filaments. Their form has to do with the orientation of the magnetic field relative to the surface of the sun.
