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:

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!
