Comet C/2013 A1 Siding Spring: an image (25 Nov. 2014)
After its historic close approch to Mars, last Oct., comet C/2013 A1 Siding Spring is still an interesting sight, though not easy from the Northern hemisphere.
The image above is the average of five, 60 seconds exposures, remotely collected with the PlaneWave 17″+Paramount ME+SBIG STL-6303E robotic unit part of the Virtual Telescope Project. The telescope tracked the apparent motion of the comet. A satellite trail is also visible. It is worth to mention that the comet was very low (15 deg) above the South-West horizon, while the sky was still affected by the twilight and by some approaching clouds.
