Comet ISON (IV)

Comet ISON (C/2012 S1) is back, but not with a bang. It looks like the comet could not keep up the brightening rate and now the predictions for the maximum luminosity have dropped quite a lot (check out Seiichi Yoshida's awesome graphs and information about comet ISON). It can still surprise us, especially as it will pass so close to the Sun, but for the moment the hopes are not that high any more. 

The comet was still in twilight when I photographed it for the first time after passing through the conjunction with the Sun. Images taken on the 3rd and 5th of September. 

Image taken with the 50 cm telescope on top of the Argelander Institute for Astronomy. 

Comet C/2012 S1 (ISON) (III)

My first color image of the awesome comet ISON. It's not very pleasing aesthetically, but it will get better with time. Check out the other two posts about it, I and II for more info, pictures and animations!

   The images were taken last night, on the 17/18th of February 2013, with the 0.5m Argelander Institute for Astronomy roof telescope, from one of the most inhabited regions of Europe, with the corresponding light pollution.
