19x1min exposures on a Canon EOS 600D, 200mm f/4, 100% crop.
Can start to see the differentiation in colour from the green gas coma and white dust tail
Not visible in my 9x63 binoculars.
I predict that ISON will gain about 1 more magnitude before perihelion as it loses elongation from the Sun. A bit disappointing for us in the southern hemisphere.
