There is a nice image from a widefield mosaic camera at the 3.6-meter Canada-France-Hawaii telescope
here. among other places. There may be more not getting wide release. By now, the comet is so big that few large telescopes have wide-enough field imagers to take it in without a major mapping project (come to think of it, last time I imaged it with our campus 0.4m telescope, it took me 12 frames). Best I can remember, the Gemini telescopes don't take in much more than 5 arcminute fields, with Subaru's SuprimeCam the giant-telescope champion at something like 3/4 degree. On top of that, it would take something even more amazing (like SN 1987A) to chase all the star and galaxy people off the telescopes with their carefully prepared schedules of multiobject spectroscopy. For something this bright, large telescopes haven't offered too much unique in the way of imaging; IR spectroscopy would be a powerful approach, though. {Truth in advertising - I did get bumped from the schedule of the ESO 3.6m by SN 1987A several months after its explosion was observed. I happend to check somewhat later and found that it was snowing for most of those nights anyway...] Also, keep in mind that not all facilities feel much urge to release pictures quickly for public edification, depending on their user communities...
