Hello,
i send you my latest h-alpha-sundrawing from 27.11.2011. I send you the positiv and the negativ
version of my drawing.
Object Name: Sun
Object Type: Star
Location: Freising-Lerchenfeld, Bavaria, Germany
Date: November 27, 2011
Media: graphite pencil, knife, digital tools (Minolta Dimage Z2 Camera)
Time: 10:50 – 13:15 MEZ
Telescope: Coronado PST (40/400mm)
Ocular: 9mm SW
My webside: www.dersonnenzeichner.de
I use a drawing pattern with lightgray sun. I draw the prominences, sunspots and
filaments with graphite pencil. For the active regions and flares i use the knife to
scrape the gray color off. On this away I can hold finest details.
Kind regards,
Michael Wendl
Object type – Huge filament and prominence
Location – Wilp, The Netherlands
Date – November 12 and November 14, 2011
Media – Pastel pencil on black paper, color with Photoshop
The largest prominence and the largest filament I have ever seen, both visible at the same time! It was a fantastic view and I made two sketches of them, two days apart. On November 14, the huge filament blew a large part of itself away from the Sun at the exact moment I was observing, creating a thin candle-like flame above the surface. A remarkable sight. Clearly the Sun is getting more active every month. What it’s got left in its suprise box while creeping towards solar maximum? Can’t wait to find out!

Our star continues to provide stunning sights as we approach solar maximum. This huge prominence, among the biggest I’ve ever seen, is visible in the hydrogen alpha wavelength, but it takes a specially designed scope or filter to see it. My 40mm Personal Solar Telescope (PST) is one such scope.
The prominence consists of superheated solar plasma suspended along magnetic field lines. It is not static, but changes constantly–sometimes the changes happen quickly and sometimes slowly. The appearance of this prominence had changed subtly by the end time of the sketch, so if you want to draw one of these monsters, be prepared to work fast!

Object name: Sunspots / Sun
Object Type: Sun
Location: Budapest, Hungary, Polaris observatory
Date: 24th September 2011. UT: 12:30-13:20
Media: Graphite pencil used on white paper
Equipment used: 200/2470 refractor, Fornax 51 (7 mm Planetary) – 352x
Dear Asod,
I would like to share my sketch about the sunspots in the group 11302. I have made this sketch with a 200/2470 refractor in Polaris Observatory Budapest. This is my first sketch with this fine details at such enlargement of the object.
Unfortunately the seeing was not the best, but still I always had 1-2 seconds when everything was clear so I could sketch what I see. It was exciting to see what fine details are visible within the umbra and not only in the penumbra.

This morning everything seemed to be right. The weather was absolutely great, the Sun was more active than I’ve seen so far this year and the seeing was above average. A good day to try sketching a full-disk h-alpha sun for the first time instead of an isolated prominence. First I made a blank disk with a soft white pastel. I took the sketch outside and filled in all the details I could see through the eyepiece of my 70mm solar telescope with white and black pastel pencils. All regions were very active, especially the middle one: it changed its shape within minutes. Sometimes little bright flare-like brightenings appeared and disappeared 2 minutes later. A wonderful sight! It took me one hour (from 08.00 UT – 09.00 UT) to complete the drawing. I scanned the (black&white) sketch and gave it a reddish color with Photoshop.

Object Type: H-alpha prominence
Location: Deventer, The Netherland
Date: July 15, 2011
Media: Graphite pencil on white paper
On July 15, I made the first sketch through my new 70mm h-alpha solar telescope. The scope showed a lot of detail, but a large prominence on the northwest limb was the most stunning feature. It was large, wide, and it changed shape within minutes. I made two sketches, one at 12.00UT and one 20 minutes later, at 12.20UT. The prom clearly changed shape an structure a bit and the base was much wider. It looked as if the prominence was falling back to the sun!
I sketched with graphite pencil on white paper, inverted the sketch and pulled all the levels to “red”) with Photoshop.

Hi,
Sun sketch made on 3 June 2011 at 19:50 – 20:06 UT in Ontario Canada with a Coronado PST Ha single stack. An interesting prom appears in the SSW
The disk image is pre-printed at 16 cm diameter on computer paper and details added with mechanical pencil, scanned into my computer and contrast-adjusted with standard scanner software.
