Details:
I managed to take a sequence of the Sun in H-alpha every day for 33 days in a row, with the exception of the 5th of June that was completely overcast.
This clip is just an animation from the 18 to the 19 of June. The full 33 day animation is on Youtube at: https://youtu.be/nHk3PjtPfqg
It has taken me one and a half month of hard labour to process all the images, find out how to animate not only the rotation of the Sun around its axis but also the surface features as well as the prominences. That eliminated the use of Winjupos as a way to go.
Instead I opted for morphing technique that simulates the 3D rotation and all the other motions while being just 2D.
I opted not to render the surface negative with might be more pleasing visually, but to keep it positive as it is in reality.
To get a smoother result I would need to take 2 or even 3 captures a day to shorten the gap but I leave that for the solar maximum that is predicted between now and the beginning of 2026.
Make sure to watch in HD on a big computer screen.
