Do lossless copies of the images from this group exist, for study, algorithm development? These are jpg (lossy) here and I do not want to waste any time playing with encoded and lossy data. Any suggestions? Where there are videos, likewise. I do not have any place to buy and run my own telescope, but I could perhaps give some comments if I could download and analyze lossless images. Before processing, and tweaking.
If someone shared a small region of the sun at maximum magnification — EVEN if it does not appear clear – those could be smaller, high frame rate, high bit size images.
The Solar Dynamics Data is available in lossless formats, but the published Internet stuff is all lossy. I call it “eye candy”.
I have extra computers to do downloads and processes. If they have to run for days or weeks, OK.
