Comet C/2013 A1 Siding Spring: an image (18 Oct. 2014)
While the world is waiting for this comet having its extremely close approach to planet Mars, 24 hours earlier of this record event, that we will share live on the web, at Virtual Telescope we tried imaging comet C/2013 A1 Siding Spring under severe conditions: the Sun was only about 10 deg below the horizon and the comet was around 15 deg below the SW horizon. Despite this, this famous, but no longer spectacular comet was there.
The image above is the average of five, 60-seconds exposures, remotely taken with the Celestron C14 + Paramount ME + SBIG ST8-XME robotic unit. The telescope tracked the comet during the exposures. The frames were 2×2 binned, with a scale of 1.2″/pixel.
