Filaments in different wavelenghts
Filaments in different wavelenghts. In CaII ion lines the filament is one big "snake" while in H-alpha and H-beta they are apart. Of course we are looking at different heights in the sun's atmosphere.
Setting: TLAPO80/480 with Sol'Ex pro 2nd Gen slit and ASI678MM camera

Sun in Barium II D2 and H-Beta (June 20)
Again, I was able to make a solar image in Barium II D2 (4554A). The image of the Sun in H-Beta was very sharp as seeing conditions were good. This is probably my best H-beta so far.
Setting: Solex Pro 2nd Gen Slit with ASI678MM and Herschel Wedge.
Tilt : 0,017 and Sx/Sy 1,04
Software : SharpCap, Inti, JSolex and CS4

Huge Prominence June 20, 2025
So far, my biggest prominence ever. Captured this on June 20, 2025 very early in the morning. When I started to scan, I kept seeing a white glance after the sundisk was away. I made sure the scans were wide enough to capture the phenomen. Unfortunately I could not compile the file using Inti as a part of the scanfield was cropped. With the help of Valerie Desnoux, I could change the settings of Inti resulting in a wider field.
The prominence is about 200.000km above the sun's "surface" and about 300.000km in length; remember this is the distance Earth-Moon.
