Faint naked-eye comet NEOWISE - 10.7.2020 at 01.00 - 10.7.2020 at 02.00 Helsinki, Haltiala Observation number 91755

Visibility IV / V

Jorma Ryske, Etelä-Suomen kosmol. seura

C / 2020 F3 (Neowise) had to be spotted even though it was hiding in the very bright northern sky in early July. The fields of Haltiala in northern Helsinki have a good view to the north almost to the horizon, so in the morning to test whether there is a comet.

At first, Capella was also hidden behind the illuminating night clouds, but when it was found, the directions were roughly known and a comet was found with 10x42 binoculars in a moment. As the shadows of the illuminating night clouds shifted so that the comet remained between them in a suitably cloudless place "placemarked", it quite easily stood out as a comet-like object even with the naked eye.

The first picture taken with an 80 / 480mm small lens tube, exposure 25x0.3s, the EOS100D's cropped image field here is 1.5 * 1.0 degrees. The branched tail is shown in the figure by more than 0.5 degrees in the approximate direction PA310deg.

With Järkkär's putty zoom in the second image, the horizon was also visible, the comet is visible with a 0.5 second exposure just as a dim almost dot 1/6 down from the top of the image.

And no matter how handsome the night clouds were illuminated, a third picture was taken of them with a mobile phone at the end of the session.

Kuittaan tuon paljain silmin näkymisen.  Kirkas koman keskustiivistymä näkyi tänään (11./12.7.) myös paljain silmin, kun osasi hakea oikean paikan.

Hiukan pilveä ja yöpilveä kiusana.
