NGC 6781 - 7.8.2021 at 00.52 Orimattila, Artjärvi, Tähtikallio Observation number 100631

Visibility IV / V

The shooting night accommodated another DS object in addition to the open constellation NGC 6709 , and the constellation was the same. This time it was an annoyingly neglected planetary nebula. One edge of the object turned out to be much dimmer than the others. The color scheme was reminiscent of Lyyra's tire mist.

      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.
