    Comet C/2012 S1 Ison: a new image (10 Nov. 2013)

    Comet C/2012 S1 Ison: 10 Nov. 2013

    Comet C/2012 S1 Ison: 10 Nov. 2013

    After several days of cloudy weather, the sky was clear again at Virtual Telescope to plan some comet observing, late in the night. Of course, comet c/2012 S1 Ison was a primary target.

    The image above comes  from the average of 8 different exposures, each integrated for 180 seconds, with no filters to use all the light collected by the PlaneWave 17″ robotic unit. Images were then aligned to compensate for the apparent motion of the object, while the robotic telescope’s mount was tracking at the apparent motion rate of the object.

    Comet Ison is showing  here a 20′ long tail, with clear evidence of a ion structure, also showing as a narrow “baffle” leaving the head of the comet. Of course, this is just a portion of its full extent.
