Solar disc after the thunderstorm

Recommended Posts

Dear all,

this morning, I woke up because of lightning and thunder here in Dusseldorf area.  After the thunderstorm had moved away towards northeast- and before the next bunch of clouds appeared, I enjoyed the sunshine on the home terrace. To maximize my joy, I set up the H-alpha-telescope to have a look at the solar "weather". 

This time I once again chose natural vine charcoal which is made of the very same atoms than the solar nucleus: carbon. The prominence on the top limb of my sketch was pretty tricky to sketch its set of needle-sharp "rays" in front of the foggy background. Let me share this sketch here as my second contribution to the solar imaging challenge:

      First the disclaimer. This is my first attempt to sketch Mars, or indeed any planet. Also, it started to rain and I had to abandon it with some urgency (hence no orientation marker). I used a HB pencil and a blending stump. But I think I can see a couple of features that match Ade Ashford's app.
      The Wratten 21 filter improved the view enormously (although you may find that hard to believe looking at the picture) helping show the surface detail and improving the seeing. I tried it the day before in my 80mm refractor, but that just made the image too dim, but on the 115mm it was very good, so I recommend it to anyone with 115mm or larger.
      I tried sketching the moon (Plato) several years ago, but SWMBO pronounced it (I'll paraphrase her here) more Feline Anatomical than Selenographical. While this one may look more like a two year's old attempt at drawing a rabbit, at least no one can confuse it with the rear end of the cat. So regardless of the criticism I receive here, I'll give it another go tonight (weather permitting). 🧐

      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.

      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:

      Date & Time: May 19th, 2020 / 1300-1330 CEST

      Size: 24 x 32 cm
      Clear (and sunny) skies!
