That's pretty cool, I wonder what they look like when on the limb?

Very best,

Best regards

This is excellent work Apollo :hamster: :bow
I have seen them many times in Eric's CaK full discs and thought it was just my imagination seeing lines :)

Me too. I’ve seen linear features in my CaK images and others, but put them down to random effects. Imagine a floor randomly filled with ball bearings, there will be well ordered domains and less ordered domains, with random threads of apparently connected bearings here and there. Is this not what we’re seeing in CaK full discs? The finer lines in the magnified views are, however, more convincing.

Time to time I see a very similar "filaments" with my CaK filter. When I set a very high contrast on the screen and "walk" over the sun disk I see such "filaments" which then disapper shortly.

My explanation: our "eye - brain" machine find out such "coincidencies" in images. Just like "canals" on Mars. As the granulation network changes, earlier visible "filaments" disappear.
