PanSTARRS C/2011 L4 on Üetliberg on 15.3.2012: the comet comes to Zürich, ARTBorghi is there to catch it!


Finally a clear sky tonight. With the help of a new and very sturdy Manfrotto tripod, up in the though wind of Üetliberg Uto Kulm panoramic-terrace , my D800 could catch PanSTARRS C/2011 L4 showing off west of Üetliberg. Thanks to the Polish guy with the brightest binocular I ever seen for helping us finding the comet.

Enjoy the pictures as we enjoyed the Uto Kulm restaurant after freezing on the top level of its panoramic antenna. Click HERE on the post picture to open the set on Artborghi PanSTARRS!

    Thanks for posting the photos, very nice!

    I was the guy with the binocular. The binocular in question is Nikon Action EX 10×50. A 10×50 binocular is usually a good choice for amateur astronomy, search the web for “binocular for astronomy” if you want to read more.

    We couldn’t see the comet with a naked eye, the air at the horizon was not clear enough. If the weather allows, it may be easier to see the comet in the next few weeks when it’s higher in the sky. A sky map showing the position of PanSTARRS C/2011 L4 can be found at

    I think the plume of steam at the horizon in the photos comes from the Gösgen nuclear power plant, which is quite exactly west of Üetliberg, so it can be helpful in finding the comet in the next week.

      Hi Tomasz thank you very much for the additional hints to let us and others find the comet again. If we’ll get a clear & not windy night, it will be the time to try with the telescope we uselessly brought up to Uto Kulm tower. Maybe see you there again !?
