M57 - 30.7.2015 at 01.30 Pori Observation number 40230

Visibility II / V

Jarkko Suominen, Porin Karhunvartijat

I prepared the tube for the coming season and at the same time decided to spot the Lyra planetary, m57 Ring Nebula. There were self-illuminating clouds in the sky interfering with the description, as well as the moon that was just rising. I also came to take pictures of those clouds at the end of the shoot.

The fog was very faint through the tube and the white dwarf in the middle of it could not be seen with the naked eye. However, the "turbulence" of the fog stood out.

      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.

Hyvin näkyy (vielä) valoisasta kesätaivaasta huolimatta!

Kiitos, Juha. Kohde oli todellakin hyvin piilossa...
