Visibility IV / V

Oh, it's nice to describe these galaxies too. I returned to the Triangle Galaxy for a long time and it is incredibly magnificent! I photographed this for two nights and the exposure for a total of 2 hours and 45 minutes.

      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.
