The entire solar disk imaged in 3 wavelengths: O-III, Ca-K and H-Alpha.
All the 3 images are the result of a stitching process.

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 ...
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.

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).
Ich wollte eigentlich nur das Equipment für die SoFi morgen checken, durfte dabei aber in H-alpha beobachten, wie die Sonne so richtig was rausgehustet hat. Es gab einen X-Flare mit Materieauswurf, allerdings seitlich weg und nicht in Richtung Erde.
Spontanes Bild mit Smartphone durchs PST. Der rote Fleck ist das ausgeworfene Gas, das schon einige 100.000 km von der Sonne (rote Scheibe) weggeflogen ist.
H-alpha image of the sun from Friday. Caught the large prominence on the east limb.
Last session in august 2024, before a long pause until december.

Two more images from the recording session on 30 august.
Each image is a mosaic composed by two panels.
The Ha filter was set up to be off-band around the 656.28 nm wavelength, on the +5 and -5 Å wings allowed by the Combo Quark. In addition, the gain was modified to according to the wavelength shift.

The Sun in H-Alpha light, 30 august 2024.
On that day, the main feature was a series of some prominences, mostly on the western solar limb where, looking at the biggest ones, pareidolia could show a gazelle, a tree and a crab.
AR 3807 was playing with its plasma tentacles.
On the south eastern limb, a small arc shaped prominence, while the active region AR 3806 and the nearby filaments were moving towards the center of the solar disc.

A view of some nice features on the solar chromosphere. The last days of august 2024 were quite cloudy and the seeing was probably not the best. The results are not amazing, but still nice.
The Sun in H-alpha light, 28 august 2024.
Three prominences and some views of the active regions 3799 and 3800.
