Yet another pastel sketch of H alpha solar disc with filaments

Recommended Posts

Dear all,

two days after the previous sketch, I made another pastel sketch of the H alpha sun showing quite well, how the sun rotated and how the filaments and prominences have changed in two days:

20190609_Sun_H_alpha_filaments_01.JPG.1d6ad75f0289e9af948b233d562cccd4.JPG

Telescope: Lunt LS 50 THa B600 PT
Eyepiece: Celestron X-cel 10mm
Date & Time: June 7th, 2019 / 1000-1030 CEST
Location: home terrace, Dusseldorf region, Germany
Technique: reddish and black Koh-i-Noor soft pastels and pastel pens on light-grey Hahnemühle Ingres mould-made pastel paper
Size: 24x31cm

Here's the direct comparison:

I struggled a bit with the white balance on the smart phone camera when taking the pictures of the sketches. Both are done on the same light-grey paper.

Clear and sunny skies!

      Dear all,
      compared to four days ago, the solar disc and the prominences looked a bit more interestingly varied. I could do a sketch during the lunch break:

      Clear (and sunny) skies!

      Hi all,
      as well today the sun is shining brightly here. I set up the Lunt to have a look at it, at first just for observing. However, somehow I cannot resist and have to do a sketch This time I've chosen reddish pastels on grey paper to better catch the color of the view in the eyepiece.

      Telescope: Lunt LS50THaB600PT
      Eyepiece: Celestron X-cel 10mm
      Date & Time: May 15th, 2020 / 1400-1430 CEST

      I heard the sun wasn't very active at the moment. Is it still active when you look through H-Alpha? (I don't really understand the difference!)
