Last night at the club meet at Porepunkah airfield, C/2013 A1 was visible in a 4.5" f8 reflector at 43x in absolute cracker skies, albeit very faintly and in averted vision. Not the hardest comet I've tracked down but not an easy one either. Movement was followed over about an hour and a half, quite substantial. Views were better in one of the member's 8" f10 SCT using a 25mm eyepiece. Quite clear, could be held in direct vision and movement was followed.
Once again, it's not the scope but the skies!
Cheers -
