M57 - 10.12.2019 at 19.00 - 10.12.2019 at 21.00 Ulvila Observation number 86810

Visibility III / V

Jarkko Suominen, Juha Ojanperä, Porin Karhunvartijat

In the evening, Juha Ojanperä and I had to start to observe the passage of the Kopler 18c exoplanet, but the upper clouds filled the sky with the halons of the Moon (a pity that the rogue did not get involved ... For both).

Before the clouds came, however, we ventured to take 10min single exposures of Messier’s 57 planetary nebulae.

      Planetary nebula is the remnant of a death star. It could be ring-shaped, disc-like or spread out rather irregularly.

      With the exception of some nearest objects planetary nebulae have a small apparent diameter and they need a rather big instrument to be visible.
