Barnard 150, NGC 6946, NGC 6939 - 3.11.2018 at 18.30 Alavus Observation number 79060

Visibility I / V

Jukka Koivisto, Suomenselän Pegasus

The clear evening did not last long as the fog already took over the skies. But little did I get to describe the subject of the evening. A bit of an awkward target right in the zenith.

    • Spiral galaxy info

      Spiral galaxy is a stellar system where there are outwards arched spiral arms from roundish (spiral galaxies) or bar-shaped (barred spiral galaxies) central condensation.

      The apparent shape of spiral galaxied depends on out observation direction. From above they are quite round. From the side they lens-shaped with a bulge in the middle.

      Generally a rather large instrument, good weather conditions and observational expereince are needed to see spiral arms. Usually spiral galaxies look like a fuzzy spots.

  • Nebulae
    • Dark nebula info

      Dark nebulae are dust in space. It obsruct the visibility of background star and bright nebulae. Thus, the dark nebulae are seen as dark clouds in space.

  • Star clusters and asterisms
    • Open cluster info

      Open cluster is an irregular group of tens or hundreds of stars. It can be visible as separate stars or a bit fuzzy spot with small instrument.

Barnard 150 näkyy tosi hienosti! Laajakulmakuvat ovat usein mielenkiintoisempia katsella kuin lähikuvat yksittäisestä kohteesta.
