The picture is not strange, the exposure is only 3 x ½ minutes. In the test NINA, an absolutely awesome imaging application with Plate Solvers (ASTAP). Fill image of a courtyard observatory (sky as a roof).

      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.
