Eratosthenes is a very dramatic and beautiful deep crater with a well-defined circular rim, terraced inner walls, a central mountain peak, but lacking its own ray system. The sketch, which is my third and best sketch of Eratosthenes so far, was done at relatively low sun-angles to bring out the shadow cast by the crater and adjacent western terminus of the Montes Apenninus mountain range. What makes this formation interesting to sketch is its linkage with the Apennine mountain chain.
In my sketch I tried to bring out the following features:
Rays from the prominent crater Copernicus to the south-west
Fine detail of the western terminus of the Montes Apenninus mountain range.
Numerous craterlets which typify the region around Eratosthenes
Internal wall terracing
Way back in 1924 Pickering noted dark patches in the crater that varied in a regular manner with time. He attributed these mobile patches to around 36 different flowering plants. Check out this old document http://articles.adsabs.harvard.edu//full/1925PA…..33..629M/0000630.000.html written by one of his associates about this.
Vesta and the Hyades
Vesta and The Hyades
Hey Artists!
Yes, this is a real old, restaurated sketch from the good old days, but it shows asteroid Vestas
movement across the beautiful Hyade star cluster over a observation time of 17 days.
I have org. 11 observations of Vestas positions, but 4 on this sketch. Info on the sketch.
I used pen and pencil on white paper (inverted).
Location: Trondheim, Norway.
I hope you like it!

Viewing the Crater Line Linne
Crater Line Linne (Move mouse over image to view labels)
This clear, cold evening provided from my location the opportunity to observe and sketch the straight line row of small craters from Linne A to Linne G. All five of these craters range from three to five kilometers in diameter. Other yet smaller craters were spotted during brief moments of good seeing but were not included in this sketch. Near the top center of the sketch the sixth bowl shaped crater Banting (5 km.) is clearly visible. South is up in the sketch so the Little Linne sequence from top to bottom is A ( 4 km.), B ( 5 km.), F ( 5 km.), H ( 3 km.), and G ( 5 km.). What especially caught my eye here on the floor of Mare Serentitatis were the fine, long shadows from each of these little craters.
Sketching:
For this sketch I used: Canson Black Ingres textured paper 8″ x12″, white and black tone pastel pencils and crayons, blending stumps, white pearl eraser
Telescope: 10 inch f/ 5.7 Dobsonian and 6 mm eyepiece for a magnification of 241x
Date: 01-30-2012 1:20-2:00 UT
Temperature: -4°C (24° F)
Clear, calm
Seeing: Pickering 5/10 – Antoniadi III
Co longitude: 347.3°
Lunation: 6.74 days
Illumination: 39.6%

Sketches of Jupiter from Polaris Observatory
Sketches of Jupiter - December 3, 2011
Dear Asod,
I send you here a montage of many sketches of Jupiter made by a group of amateur astronomers in Polaris Observatory, Hungary, Budapest.
We have monthly tutorials for anyone who is interested and we are going through all types of objects. When it came to the planets, unfortunately the weather was awful, so we decided to make a tutorial of sketching the Jupiter from a photo done a few days before. Here we got, everyone could practice observing and sketching. Even those joined who have never sketched before, and all of them suceeded, as you can see.
The sketches were made by: Szabolcs Kiss, Attila Pilisi, Time Kovesdi Farkasne, Peter Molnar, Ervin Katona, Viktor Farkas, Tamas Jakabfi.
Media used: graphite pencils and pastel pencil used on white paper
Date & time: 3rd December 2011 (from a photo made a few days before).
Place: Polaris Observatory, Hungary, Budapest
Clear Skies,

Sporadic Meteor over the Castle of Forcalqueiret
Sporadic Meteor
January 23, 2012 at 7:37 p.m. local time, I saw this meteor fall. It seemed to fall on the castle of Forcalqueiret in Provence, already so ruined …
This meteor belongs to the sporadic family, no known shower exist at this time of the year. Slow, it has about 3 seconds to disintegrate by emitting a beautiful ocher yellow light.
My sketch was made naked eye in the cold of this early winter evening. We can see the sky from the Pleiades to the feet of Orion, passing through the Hyades in the constellation Taurus. I tried to take account of different colors like Betelgeuse and Rigel, respectively red and blue. The Great Nebula in Orion also shows a little pink shade than the surrounding stars.
I made this sketch on white paper with caracole pencils, using directly the correct reverse colour black for white, blue for the meteor, light blue for Betelgeuse and M42, and yellow for Rigel. The final work is to invert the scanned sketch.

The Seven Sisters
The Pleiades
Hello.
This is my first sketch presented on ASOD.
Last night I got a clear sky and I started off by looking at one of my favorite objects: M45. The sky was very clear and I was surprised to see a small hint of nebulosity near Merope but it was really faint, almost invisible.
The Seven Sisters plus ofc Atlas and Pleione were shining with a bright light which I tried to mark on my sketch.
I used a 150/1200 Dob , 25mm Plossl Eyepiece, x48 mag (I spread the sketch in two fields, in order to get all the detail.)
Object Name : Messier 45, Pleiades
Object Type : open star cluster
Location : Marosvásárhely, Romania.

Venus – January 3, 2012
Venus - January 3, 2012
Hello everyone,
here you can see my first sketch of planet Venus. I saw there one big spot near the terminator. And other spots you can see on the picture. I used my newtonian telescope (8 inch), 8mm Hyperion and two filters. Other parameters are in the picture.

The Wings of M42
Messier 42
Hallo!
This is my first sketch presented online. I’m not experienced with drawing but this is my third sketch of Orion nebula! I needed 90 minutes for the drawing and it was really cold about -6°C. The transparency was really good that evening for my observation point with a magnitude of 5m3.
I used a Newton 150/750mm with OIII-Filter. The magnification is 100* and the field of view is 0,52°.
Object: Orion Nebula (M42 & M43)

Dumbbell Nebula
Messier 27
Object Name: M27 (Dumbbell Nebula)
Object Type: planetary nebula
Location: Płaza, Poland
Date: 25.09.2011
Media: graphite pencil, white paper, inverted
Dumbbell Nebula (M27) is a beautiful planetary nebula located in our galaxy. You can observing it at warm, but very short summer nights. When you’ll look at eyepiece, you’ll see the big nebula and a hundreds of stars, because this nebula is cut by one of our galaxy’s arm.
Mare Imbrium
Mare Imbrium
Aloha!
I submit my most recent sketch of a close up detail of Mare Imbrium of 1/1/12. First observation of the New Year for me & first attempt using white pastel & black artist paper for a moon sketch. I found it a bit frustrating at fist since I have always sketched in black charcoal on white paper for the moon. After I got the hang of it I really enjoyed the texture & detail I could create with the black paper.
I am currently working on an Astronomical League Certificate for the moon and I am amazed how much more detail I must learn to sketch. I want to know what every crater & peak of light is that I am recording on paper.
On this night I used my 8” Dobsonian & 14mm Explore Scientific EP
Seeing was excellent, Temperature 65 degrees F from 4000 ft elevation
Maui, Hawaii
Thia Krach
Barnard’s Merope Nebula
IC 349
I have thaught it would be useful for ASOD members to have a sketch of this very little nebula, hidden in the light of Merope. It is very difficult to see, unless the seeing is very good, and it was the case.

Maia Moon
Gibbous Moon
My 9 year old daughter Maia was out exploring the moon last night through our 8” Dobsonian. She used 14mm & 27mm eyepieces to observe the January 1st, 2012 moon. She recorded details using an Astro Sketch form I had on hand.
The night was clear & seeing was good, and in her words “The craters were huge”
