Comet C/2012 S1 Ison: spectrum (17 Oct. 2013)
Above is a zoom on the spectrum of comet C/2012 S1 Ison we took a few nights ago, using a 100 lines/mm grating and the Celestron C14 robotic unit part of the Virtual Telescope....

Comet Ison is not the only interesting comet around these weeks. Early last September, comet C/2013 R1 Lovejoy was discovered and it showed to be an interesting object. Comet Lovejoy will be a nice sight...
Despite the very bright (full) Moon, at Virtual Telescope we decided to image the same comet C/2012 S1 Ison. So, early in the morning of 20 Oct. 2013, the PlaneWave 17″ robotic unit was slewed...
After more than one month since the previous observations, the Virtual Telescope visited again comet C/2012 S1 Ison, while it approaches the Sun. At the moment, the comet was visible in the morning sky,...

Since its discovery in Sept. 2012, comet C/2012 S1 Ison attracted a lot of attention. Early evaluations of its orbit showed a great potential for a memorable show, with the most optimistic scenarios reporting...
While waiting for comet Ison, we have another nice comet to observe. It is comet C/2013 R1 Lovejoy, discovered by T. Lovejoy early this month. Early in the morning of 14 Sept. 2013,...
While comet Ison is approaching and comet C/2013 R1 Lovejoy was just discovered, we wanted to observe another comet, too: comet 2P/Encke. It is a periodic comet orbiting the Sun once every three years, being...
After a few days of cloudy skies, the weather decided it was time for another clear night at the Virtual Telescope site. Early in the morning of 14 Sept. 2013, the PlaneWave 17″ robotic...
While it approaches the Sun, Virtual Telescope imaged again comet C/2012 S1 Ison. The comet just 18 deg. above the eastern horizon, and the weather was changing, so less than ideal conditions. The PlaneWave 17″...
After the first image of the season, Virtual Telescope imaged again comet C/2012 S1 Ison. The comet just 17 deg. above the eastern horizon, but it looked a less extreme situation than the previous...
Above is the first image of comet C/2012 S1 Ison taken with the Virtual Telescope after its conjunction with the Sun. It was an hard observation, with the comet just 12 deg. above the...
On the video below, comet C/2011 L4 “Pan-STARRS” shows its antitail and motion across the stars. Each frame comes from a 120-seconds exposure, taken with the 17″ robotic unit part of the Virtual Telescope...
Comet C/2011 L4 Pan-STARRS is still giving a great show in the northern skies. After it was visible at sunset by naked eye, it is now visible all night with a telescope, if you...
The Virtual Telescope visited comet C/2011 R1 McNaught, a nice object which reached mag 7 last April. It is still a nice view in the northern Spring skies, as the picture above clear...
