Keep on the trail, if you can, see if you can get some afocal images of it using a widefield eyepiece on your telescope and a short exposure (2 to 5 secs) with your 400D @ 1600 ISO
Thanks all! Outbackmanyep, Michael's latest image shows 5 degrees of tail - wow! Mine faintly shows about 3 degrees.

Afocal's no good, as I can't track with my scope - even a few seconds gives considerable trailing. Might try it again in a few days - bit of a juggling act really, between dimming comet, darkening sky, and shooting off a tripod with limited equipment. Using the kit lens, I can shoot wide (18mm) for about 30-sec without bad trailing. If I zoom in at 55mm, can only go 10 sec, and restricted to F/5.6 max.

Lesser of two weevils really - stay wide & opened right up, with lots more subs! And better focus ! Just happy to get a memento of the comet's visit I guess.........

Cheers -
