ISON by Moonlight

ISON by Moonlight

Click image to view the highest image resolution

The sky was very bright early this morning with the moon just two nights past full. ISON is brightening quickly and growing a longer tail. The comet is midway between the orbits of Mars and the Earth. It is 1.27AU from the Sun. The field of view is 29.4' x 44.67' or nearly as high as the full moon. I estimate the tail to be around half the width of a full moon or around 15' long.
