A quick sketch from the 1st September (sorry - date is wrong on the image).
M15 was still fairly low in the east but the central condensation of stars really stood out, even in a 5.5inch scope. The bright field star intruding on the edge of the image was distracting. If I had a tracking mount I'd have banished it permanently!
A lot of the extended GC was on the threshold of vision and the resolved stars faded in and out.
M15 will always have a special place for me as it was the first GC i ever saw 😍
Thanks for looking.

Dear all,
these days we have a sunny and hot summer over here. Today I tried to capture the "aura" of the sun caused by some dust in our atmosphere when doing the pastel sketch of the H alpha solar disc. I spent almost half an hour with the solar disc and its aura and then just 15 minutes for the proms and filaments. So here's the result:
Telescope: Lunt LS50THaB600PT
Eyepiece: Celestron X-cel 10mm
Date & Time: June 26th, 2019 /1030-1115 CEST
Location: home terrace, Dusseldorf region, Germany
Technique: red and orange Koh-i-Noor pastels and pastel pens on black Canson Mi-Teintes pastel paper
Size: 24 x 32 cm
Clear (and sunny) skies!

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:
Telescope: Lunt LS 50 THa B600 PT
Eyepiece: Celestron X-cel 10mm
Date & Time: June 3rd, 2019 / 1000-1030 CEST
Location: home terrace, Dusseldorf region, Germany
Technique: natural vine charcoal on white Hahnemühle Ingres mould-made pastel paper
Size: 24x31cm
Clear (and sunny) skies!

Dear all,
as suggested by Hughsie, here's my pastel sketch my contribution to the solar imaging challenge.
Telescope: Lunt LS50THaB600PT
Eyepiece: Celestron X-Cel 10mm
Date & Time: May 29th, 2019 / 1630-1700 CEST
Location: home terrace, Dusseldorf region, Germany

Like all of my astronomical sketches , I did this one directly at the eyepiece. The picture of the sketch is taken with my smartphone and just cropped.
Clear (and sunny) skies!
