A large prominence on Sun’s SE limb 1st June 2014. Hard to imagine that these glowing clouds are cooler hydrogen gas surrounded by hotter transparent plasma. Sketched at the eyepiece with Derwent Watercolour pencils on black paper. SolarMax60 H-Alpha ‘scope 50-80X. Location UK.
Aloha!
I was enjoying the Sun this morning and trying to decide how to represent the most prominent features. Sketching the Sun has just not gotten me the feeling that I can really represent it as well as I would like to as far as colorizing goes. I like using black paper but it isn’t smooth enough whereas plain white paper is. But when I have tried to add color later, it just loses what I see in the scope.
So today I tried a little something different. I like how some inverted blue colors really become the right colors for the Sun. So I put some oil pastel colors to paper & inverted to see what I could use. The nice thing about the oil pastel is I can scratch off small little lines to try to get the details of the solar surface. I had to think in negative to produce the sketch in order to preserve black, white and the different tones of red. This is my 1st attempt using this technique and I am not entirely happy with it but it is a bit of an experiment.

Since I exchanged Belgium for Sweden last year, I am faced with lack of astronomical darkness since mid april. Astronomical darkness (sun below 18 degrees of horizon) will only return end of august. Therefore I will be concentrating drawing more suns and moons instead of deepsky. The positive side to this is that in Winter time it ‘s astronomical dark at 5.30PM already 🙂
I have used my 21 years old TeleVue 101 SDF apochromate refractor, teamed with an (also old) Daystar 0.7Ă… h-alfa filter. A Barlow is needed to reach the required f/30 focal length. I am using a TeleVue alt-az Gibraltar mount.
I have added a picture to show the observation location. I have reached SQM 21.6 a number of times already.
Hope you like it.
best regards

From time to time, with friends, we animate minor scientific events in small Provencal villages.
Today March 19th we were in Varages with the local AAP astro club. Fifty kids and residents came to have a look at our star’s volatile proms in H-alpha and some nice spots archipelago’s in WL. We used 3 refractors, a Lunt 35mm a Coronado 60mm and a classical 102/1000 for the WL. The annexed sketch was done in H-alpha, directly on site, to show to the spectators, what can be seen through our material. In parallel some of our wife’s are trying to explain that our sun is a star.
Clear sky to you all !

Object Name Sun
Object Type Sunspot 1575 and crown
Location NĂ©oules Provence France
Date 22 sept. 2012 – 13h TU
Media (graphite pencil for the spot, red pastel for the crown, two different white papers, Paint.net)
I made two separate sketches, one in H alpha via a classic PST for the crown, the second one through a 1000/102 refractor with solar continuum filter for the spot.
I used several eyepeaces.
The compilation was done with the freeware software : Paint.Net
Conditions were perfect, the sun was hot here… !
Clear sky to you all

Hello artists
Just a few hours after the great sketch of Stratos Tsanaktsidis, I had the opportunity to draw this one. I use a common H alpha PST Coronado.
My technique is quite original, after a light circle portion made by a graphite pencil on white paper I use directly a pure watercolour “green emerald” to sketch the solar surface on a water base and then the protuberances on the dry part of the sky, taking into account that light green will become dark red and vice-versa. Then I just have to invert the colours after scanning. The white sky is becoming black while the green part is becoming “H alpha red”.
Right, I add the approximate dimension of the earth and the moon orbit.
Clear sky to you all

The sun’s activity is very important in this moment, causing greats eruptions that I drew the best I could. Note that few sunspots appear (maximum 2). The dark lines on the sun are eruptions pointing in our direction.
