M51 - 23.8.2015 at 01.30 Pori Observation number 41421

Visibility II / V

Jarkko Suominen, Porin Karhunvartijat

The M51 galaxy from the constellation of Hounds also became exposed. This time the tripod had a sturdy ground under the tripod, and so it didn’t sink at all (like the last thing happened to me when describing this item ...) and the trend remained fine.

    • 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.
