Hei Artists!
Not many artists on ASOD make sketches of the structures in the inner coma of comets.
Very interesting things may happen in the light coma, which is difficult to show photographic.
The spirals in the comet Hale-Bopp were sharp (as a painting) visually, but at best diffuse on
photos! Therefore it is very importent to document visually and on a sketch.
By using high power on the telescope you can observe details (jets) near the nucleus, and
over a period of time other interesting phenomenon, the most dramatic : you may discover a
breaking of the nucleus!
Such structures is also best seen against a lighter sky, as with observations of Venus.
Remember: Many things can happen in the head of comet ISON later this year!!
Back in 1976 , I could observe the splitting in comet West (3 parts)!
I used watercolor crayons for the sketch.
loc. : Trondheim, Norway.
Clear sky and best wishes from Per-Jonny Bremseth!

Height above the horizon 36 º Observation at sea level in Barcelona (Spain)
Media: pencil in white paper, Microsoft Paint
Notes:
Horizontal image investment because used diagonal mirror.
The predominant color on the planet is a very pale yellow (at other times showed an intense golden) contrasting with some greyish belts with ill-defined irregularities. It clearly shows the shadow of the planet on the rings.
The Cassini Division shows a high contrast and a black is intense and well defined.
I could clearly see the satellites Titan, Rhea, Dione. Tethys only very weakly.
Enceladus, I’d be on the limit of this equip, but It was not possible to distinguish. Mimas is beyond the scope of this opening.
Hello asod, this sketch show is pretty irregular galaxy. During the observation, I could visualize the extreme deformities, without much effort. A large object that caused a great sensation through the eyepiece. Do not stand by its size but by its peculiar shape.
Regards.

Notes: This sketch was executed with a Celestron C925 on a CGEM with a Swan 40mm EP and a Williams Optics 45º erecting prism diagonal at 58X. The wind was 10mph, Temp: 47ºF, Humidity 24% under a first quarter moon at 2130. The Lit. Rho is 12.8″, Theta is 280º. I measured the pair with a Meade 12mm Astrometric EP and obtained an average Rho of 14.8″, and average Theta of 218º.
I am interested in the nebulosity of the three NGC objects that are included in the field of view. I plotted 25 field stars including one outside the F.O.V. to the west and two outside the F.O.V. to the WSW.

Bonjour,
Voici un dessin de la comète C2011L4 Panstarrs fait avec un dobson de 345mm, focale 1504mm et un oculaire de 40mm (37 fois de grossissement)
Elle est encore bien brillante et très belle à voir.

Hello,
Here is a Sketch of the comet C2011L4 Panstarrs done with a 345mm Dobson, 1504mm focal length and an eyepiece of 40mm (37 times magnification).
It is still bright and beautiful to see.

Hi All. M67 has many nebulosity in the cluster.
And M67 is one of the oldest cluster in the sky.
I give a guess that is related to nebulosity…? I don’t know exactly 🙂

Hello friends artists,
this is my sketch of the Panstarrs, one of the comet of 2013. The tail of the comet was long enough and the head was very light. This is my first comet and I liked it so much. I observed it with a 100 mm telescope, at 7,30 p.m. It was visible with naked eye like a 2 magnitude star. Moreover I observed it with a 20×80 binocular, and it appeared equal, more or less.
Hope you like this sketch! And I hope you understand my english!
