Natural charcoal sketch of the summer H alpha sun

Recommended Posts

Dear all,

today at 30°C, I had a look to the H alpha sun the first time in summer this year. Here's the natural charcoal sketch of it:

That's a very tricky thing to do!  Looks like you nailed it! Great sketch

A figure of speech ‘you have to be joking’ a work of art is what it is. Like a photo negative from back in the 35mm era. Well done.

Dear all,

thanks a lot for your great feedback!

Inspired by Marvin's comment, I created the negative of my sketch to see how it would have appeared as black and white photo in the old days:

This reminds me to my chalk sketches of the full moon.  Frankly, I prefer the negative charcoal version of the solar sketch. But it was a nice experiment at the PC. Thanks for heads up.👍

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:

      Eyepiece: Celestron X-cel 10mm
      Date & Time: May 19th, 2020 / 1300-1330 CEST

      Technique: red and orange Koh-i-Noor pastels and pastel pens on grey Canson Mi-Teintes pastel paper
      Size: 24 x 32 cm
      Clear (and sunny) skies!

      Dear all,
      this morning, before going off to work, I started the day with a lunar sketch of lunar sunset before sunrise at home. I had put the 5" MAK outside over night, so it was properly cooled.

       
      Telescope: Celestron NexStar 127 SLT
      Eyepiece: Explore Scientific 6.7mm/82°
      Date & Time: January 16th, 2020 / 0715-0745 CET
      Location: Home terrace, Dusseldorf Region, Germany
      Technique: Koh-i-Noor chalk, extra charcoal and whitecoal pens and pieces on Seawhite of Brighton black sketching paper
      Size: appr. 20x30cm
       
      Clear skies!

      Dear all,
      yesterday evening I have chosen the lunar crater J. Herschel (named after British astronomer John Herschel from 19th century, the son of William Herschel) which exposed a pretty convexed floor in the rising sun. The crater has a diameter of about 150 km and lies at the northern "coast" of Mare Frigoris.
      The sketch starts with Harpalus in the South, then you can see the 24 km crater Horrebow (named after a Danish astronomer from 17th century) just at the southern rim of J. Herschel. At the northern end of my sketch we have the 71 km crater Philolaus.
      The dominating crater J. Herschel (too be precisely a walled plain) has a quite rough surface which is said to be caused by ejecta from the impact that formed the Mare Imbrium. This rough structure and its convexed shape resulted in a nice three-dimensional appearance.
      Southeast of it, I sketched the secondary craters J. Herschel F and la Condamine B which are located in Mare Frigoris.
      So here's the sketch:

      Telescope: Celestron NexStar 127 SLT
      Eyepiece: Explore Scientific 14mm/82° (due to the poor seeing, I couldn't go for the 6.7mm/82°)
      Date & Time: January 6th, 2020 / 1845-1945 CET
      Location: Backyard, Dusseldorf Region, Germany
      Technique: Koh-i-Noor chalk, extra charcoal and whitecoal pens and pieces on Seawhite of Brighton black sketching paper
      Size: appr. 20x30cm
      And finally here's a photo of my observation place:

      Clear skies!
