One comet and one vanished comet

[NickH]

So, from home last night, here's a stack of 15 x 180s subs in CLS filter from the Atik4000/mono TMB105 F6.2

And from the past week of trying with the 2m Faulkes North scope, two images of where C/2010 X1 should have been, and isn't, we had a limiting magnitude of 20.5 and found nothing in the field where it should be, which tally's with multiple other observers results...looks like it's completely gone now (well as far as we can see with a 2m scope and a 97% QE CCD with 13 x 20s exposures)
