I tried to image what could be left of comet ISON and I unfortunately have to say that there is nothing that I can see down to about mag 16.5, not even a small condensation. Total exposure of 14m30s. Crop (25' x 25') of full field of 54' x 36'. The comet is not visible even though stars down to about mag 17 are seen.
