On 28 Dec. 2014 the sky was very clear, despite a setting first quarter o f the Moon, so we imaged comet C/2014 Q2 Lovejoy again.
The image above comes from the average of seven, 120-seconds unfiltered exposures, remotely collected with the PlaneWave 17″+Paramount ME+SBIG STL-6303E robotic unit part of the Virtual Telescope Project. The telescope tracked at the apparent rate of the comet. The object was at 23 deg. of altitude above the horizon.
This is a quite high resolution image, showing about 25′ of tail, but at high resolution and, in fact, it is amazing to see the complex structure of the inner, ion tail. The image shows both the ordinary and inverted palette, to grasp every subtle feature.
