  1. The Bubble Maker - WR134 in Cygnus. A Wolf-Rayet star sculpting a spherical emission bubble with its relentless stellar wind over millennia. Imaged in Hubble palette mapping (HOS). NGC 6883 and β² Cygni also in the field.

  22. Heute mal wieder die #Sonne in #halpha. Mosaik aus 7 Frames und Zeitraffer über (leider nur) 10 min. Wetter / Seeing war klasse. Dafür hat die Technik gezickt ...

  23. Six images of the Sun in H-Alpha.
    During that session, the solar limb didn’t show any relevant prominences, so all the data was focused on the active regions.

  32. I just had wanted to check the equipment for tomorrow's solar eclipse, but was able to observe in H-alpha how the Sun spit out a lot of matter. There was an X flare with a coronal mass ejection. It went sideways and not in the direction of Earth.

    Potato quality image with my smartphone through the PST. The red spot is the ejected gas, which has already traveled several 100,000 km away from the Sun (red disk).
