Looks good! I'd back off on the sharpening a bit, but that's just my taste. I've also found through trial & error that keeping exposure down and pulling up highlights a bit to taste in post gives a better (to my eyes anyway) result. In early test shots I was clipping the red channel a lot.
I've tried manual and auto-focus with my chosen lens (Panasonic 100–400mm on a GX8 camera) and have decided to go with AF for the eclipse. I put the focus point at the sun/sky boundary, which seems to work pretty well. Though earlier this afternoon I AF'd on the central sunspot area and that worked too. I set the self-timer at 10 secs followed by a 3-shot burst. There's some wind here today so about half the shots showed some blur at 1/320 sec.
I've set white balance down ~2800K: still gives a warm result but not baked.
I also see some hot pixels in my pics, normally not visible at all. Not likely stars: the sun is
intense and so exposure times are too short.
For kicks I took an infrared shot today via a 900nm (or so) low-pass filter and have attached it. This works but doesn't really offer anything worth doing again.
Clear skies!
