Sonnenflecken / Sun Spots - 20211227Please view this
Seeing Animation (short video) made from the single frames used for my image.
Please consider also comparing my result with
NASA's continuum photo from this same day and time.
Although the sky looked mostly blue and clear with the sun really bright, high clouds (altocumulus + extended cirrus) passed by rather fast all the time. I couldn't get a single minute without clouds partly or wholly covering the sun. When ever it seemed possible, I started a capturing session – 5 sessions all together.
The rapidly moving thin clouds covered the solar disk enough so that the smaller and weaker sunspots remain invisible in the single frames and even after stacking more than 200 DSLR images. Even the large sunspots in the middle remained blurry no matter how hard I try to sharpen them.
Frustrating.
At 13:00h (CET) the sun entered a "blue hole" with no visible clouds for one or two minutes. I hurried out again – though I had already given up after 4 times from morning to now. In this 5th session I took 240 DSLR frames (RAWs of course). Happily, I could see the small sunspots already in each single shot. And after stacking, my today's image finally lookes quite nice.
The seeing was bad but by far the best I had today – please view the
Seeing Animation made of my 5th capturing session's single shots.
