Martin reported four good, consecutive clear skies using itelescope.net's Siding Spring facility.  From 2014-09-26 to 2014-09-29 he imaged 2012 K1 Panstarrs, all just before pre-dawn twilight.  Equipment was 0.51-m Planewave scope operating at f/4.4, with the FLI Proline 09000 CCD. 

Exposures were 120 secs and all were processed in the same way.  The comet was in western Hydra at a declination of about -10 degrees.  It looks similar in each shot but there is some variation, especially on the 28th (lower left) when the ion tail was at a slightly higher angle.  The (approx) 135 degree angle between the dusty tail (lhs) and the gas tail (rhs) is quite dramatic, due to our viewing angle wrt the comet's orbital plane.  Details are on the caption.
