Thanks Scott, yours turned out quite well too, not sure I want to spend so long tracking on it myself though
I'll try some 85mm photos if I get some clear sky in the next week.
I think the behaviour is fairly typical of comets that disintegrate- just a streak of coma left with no condensation- just that C/Lovejoy lost so much more material in a short time than most comets, so the tail was much larger, but there is nothing left to replenish it now.
