Large prominence on southeastern limb of the H alpha sun

Dear all,

today morning I had a look at the GONG network images on the internet and set up my telescope to have a look at that awesome large prominence on the southeastern limb of our home star. First I concentrated on a sketch of just that wonderful prominence. After that, I created - as usual - a sketch of the full solar disc. I noticed that the prominence already had changed during my sketching time.

      Dear all,
      luckily we have excellent weather here today and I could use my lunch break for observing and sketching the solar exclipse.  When sketching, I tried to "mentally" mirror the view in the EP back to non-mirrored orientation. I hope this went well. The progress of the eclipse shown in the sketch is from 1235 CEST.
      Here we go:

      Telescope: Lunt LS 50 THa B600 PT
      Eyepiece: Celestron X-cel 10mm
      Date & Time: June 10th, 2021 / 1215-1245 CEST
      Location: home terrace, Dusseldorf region, Germany
      Technique: reddish Koh-i-noor pastels, pastel pens and charcoal pen on black Hahnemühle Ingres mould-made pastel paper
      Size: 24x31cm 
      Clear skies!

      Dear all,
      yesterday afternoon, the forecasts for the evening were good so I set up the 10" truss-tube Dobsonian on the terrace for cooling down. Actually in the evening the sky wasn't as clear as expected but the cirrostratus luckily did not harm too much. It could have been brighter but anyway ...
      So I tried my new 2x focal extender with the 10 inch scope for the first time and magnified up to 370x. Seeing was okay and I really enjoyed travelling along the terminator from Plato via Copernicus down to Clavius. For the 10"er the focal extender is really an enhancement when viewing the moon and conditions are okay: I saw much more detail in Clavius as I have ever observed before. 
      This would have been a good sketching target but finally I decided to go for a sketch of the magificient Copernicus (named after the famous Polish astronomer by Giovanni Riccioli mid of the 17th century): 
      The crater floor was still completely in darkness, one could only see the bright, round rim of this 93km wide crater. The terraced slopes were just partly in the lunar sunrise yet. Obviously the central peaks are as expected lower than the rim - they were still hidden in the darkness. The two craters north of it are Gay-Lussac A and Gay-Lussac on the way to the Montes Carpates with their eastern parts already visible.
      Here's the sketch:

      Telescope: Martini 10" f/5 truss-tube Dobsonian
      Eyepiece: Explore Scientific 6.7mm/82° with Explore Scientific 2x focal extender
      Date & Time: Jan 22nd, 2021 / 1900-2000 CET
      Location: home terrace, Dusseldorf region, Germany
      Technique: Koh-i-Noor charcoal, whitecoal and chalk blocks and pens on black sketching paper
      Size: 11"x11"
      Clear skies!

      Hi there, starting to get somewhere with my C11 HD Edge. On the 22nd got this one of M1 Crab nebula, in h-alpha. Used the 0.7 focal reducer, bring the FL to 1960mm. The camera was an Atik 314L+ mono. The filter was a baarder 7nm. The mount was a Ioptron CEM120, guided off axis with PHD2.

      My days for solar imaging are coming quickly to an end due to winter.
      This may be my last image of the year,   (hopefully not!!)


       
      A very spectacular prominence!!!  (unprocessed with 300 stack)

      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
      Location: home terrace, Dusseldorf region, Germany
      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!
