Name: c/2011 L4 panstarrs
Type: Comet
Location: Frosinone, Italy (near Rome)
Date: 21th march 2013
Media: graphite pencil for the first sketch then digital tools (gimp)
Here’s my sketch of the Panstarrs, made from Frosinone. The sky was bright when i observed the comet. It was visible with naked eye like a 2-3 magnitude star… I could see it after 7.10 pm. With the binocular the comet shows a bright core and a fuzzy tail about 1° long.
Today’s sketch-“almost full” and a bit misted Moon. 🙂
TelescopeCapella 41cm + UWA SW 22mm, sketched in pencil, using “my favorite technique of intentional negative” and then inversionof the sketch!

Sketch details:
Object Name: Almost full Moon.
Object Type: Moon.
Location: Poland, Oborniki
Date: 25-03-2013
Equipment: Newtonian telescope 409/1800 (Capella 41), and 22 mm eyepieces
Object: – Artist: Robert Twarogal (Ignisdei)
Title: Plato crater
My name: Silvia Fabi
Object name: Plato
Object type: crater
Location: Ferrara
Date: 18/02/2013
Media: white pencil and black paper
Seeing: I/II (Antoniadi scale)
Description: this crater has a diameter of 109 Km and it’s deep only 1,0 Km. It is located in the North Pole of the moon.
Clear nights this winter from my New Jersey location have been few so when the night of March 9th presented a clear sky I took advantage and did several sketches of open clusters in the Auriga and Gemini region. Submitted here is my sketch of M37 which I believe turned out to be the best sketch of the lot. A beautiful densely packed cluster of stars in Auriga M37 reminds me very much of the open cluster M11 in Scutum.
Location – NJ, USA
Telescope – Orion Astroview 100 Refractor, 32mm Plossl, 2x Barlow, 37.5x
Media – Laptop computer using MS Paint and MyPaint programs
Probably my best Jupiter of the season so far, a 6 hour strip map showing over half of the surface of the planet which I drew back on the night of 05-06 December 2012. I made the drawing with my 8 inch Newtonian Reflector here in Leicester, UK. I make the original drawings at the telescope in black and white and then use water colour pencils to make a colour version indoors.
Best wishes,

Sirsalis and Damoiseau Region Hover cursor over image to view labels.
Aloha,
I submit a lunar sketch of the Sirsalis & Damoiseau region bordering Oceanus Procellarum at the western region of the Moon created almost a year ago. What a wonderful area to explore with interesting concentric craters of Damoiseau & the double crater of Sirsalis at this angle of light. Unseen Grimaldi lies in the darkness to the west.
Object: Lunar craters Sirsalis & Damoiseau @ ~13 days lunation
Telescope: 12.5” Portaball 9mm Nagler 169X
Location: Maui Hawaii, 4000 ft elevation
Date: 2/4/12 7:45pm
Medium: Black art paper, white & black charcoal
Optics: Celesctron CGEM1100 (SCT 11” f/10), Hyperion 10mm (280x), FOV 15arcm
Media: Graphite pencil on white paper, inverted scanning
Notes: This observation was made during one of the few clear nights of the past winter period with tempertaures dropping to minus 10°C. Galaxy NGC3079 is one of the better objects in the Hershel 400 list and was at first impression quite difficult to see with diffuse and faint impression. When using averted vision the object displays a richdom in details with an overall flocky appearance, 6:1 elongated and a faint irregular core that extends to the north in a triangular brightening. The southern core area is very flocky. Two bright areas are clearly visible on both sides of the core, of which the detail in northern area is more explicit, sharply defined with a darker area towards the east and resembling a second core. A real nice object!
I’ve been itching to have a go again at Alphonsus for some time. Along with its two buddies, Arzachel (to left) and Ptolemaeus (at right), this trio are a time line of Lunar history.
Ptolemaeus is the oldest. The crater floor is totally flooded, even the central peak is covered. It was fromed when the Moon was still very hot and lava readily flowed with a large impact.
Arzachel is the youngest. The crater floor is intact with no flooding, the crater walls are terraced with land slides both inside and outside of the crater.
Alphonsus sits bewteen the two in age. The crater floor is only partially flooded with the central peak still visible. The Moon has cooled since Ptolemaeus and lava flow has slowed. BUT, volcanic activity was still occuring after the flooding process had stopped. This is seen from the pyroclastic deposits that sit within Alphonsus. Four deposits lie within this crater and are marked in the labelled pic, and are seen as the darker shaded areas that are easy to see through the eyepiece.
Quite remarkable to consider that from here on Earth we can see the effects of ancient volcanism on a body that isn’t Earth.
Another treasure of the night was the Celestron Ultima LX 8mm eyepiece I used. These eyepiece are much underrated, but are surprisingly good. The 8mm in particular is easy to use for extended viewing. It made the 2.5 hours much more bearable, and my eyes were not as fatigued as they have been after with other sketches that have taken less time to do. It’s one of my favourite eyepieces.
Object: Pyroclastic deposits in Alphonsus
Scope: C8, 8″ SCT
Gear: 8mm Celestron Ultima LX, 250X
Location: Sydney, Australia
Date: 19th March 2013
Media: Soft Pastel, charcoal and white ink on A4 size black paper
Duration: approx 2.5 hrs
I send once more one sketch of PANSTARRS.
This time in lower magn. (50x). the comet is now easier seen with naked eyes
and fine in binos as it was higher on the sky on darker sky.
The faint dust to east was interesting and the sharp edge to west.
Info on my sketch..
I used pencil on white paper and inverted in colour.
The observation was done near Trondheim, Norway.
Thank you very much on the nice comments on my sketches!!
