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!
Thanks for the great sketch & write up. Learned something new today!

Per-Jony,
Excellent, I also remember seeing and sketching those hoods back in the spring of 1997. Well done.

This picture reminds me the great comet of 1997. Thank you.
