perhaps the best combination of surface filaments, sunspots and prominences i've seen this year

| Sun 2025-06-28 19:12 UTC, 19:20 UTC Ha composite (difference) overexposed version for outer filaments combined with negative of the central detail |
 |
| Sun 2025-06-28 19:12 UTC, 19:20 UTC Ha composite to include faint outer prominences |
 |
| Sun 2025-06-28 19:12 UTC Ha color version |
 |
| Sun 2025-06-28 Ha vs continuum (off band) conventional sunspots vs plasma filaments and prominences |
Image details:
I tried BiggSky blind deconvolution on the images
I have to say it was amazing on the full disk
one click and it was as good or better than tons of fiddling with wavelets in registax
unfortunately blind deconvolution failed miserably on the higher exposure capture for the outer prominences--it can't handle clipping well.
the file management is still a bit clunky, but it's still in development.
looking forward to trying it out on planetary images.
