Comet ISON in color and a recent ISON shot by Bruce Gary

Spaceweather.com has an interesting post today with contains a few images of Comet ISON in color, which were taken by Michael Jäger in Austria.

Spaceweather is reporting that Comet ISON can now be seen through mid sized backyard telescopes.
The image above which Miachael took shows the comet as green.


"ISON's green color comes from the gases surrounding its icy nucleus. Jets spewing from the comet's core probably contain cyanogen (CN: a poisonous gas found in many comets) and diatomic carbon (C2). Both substances glow green when illuminated by sunlight in the near-vacuum of space." - spaceweather.com

Below is an image that amatuer astronomer Bruce Gary took of Comet ISON on the 6th of October.
