Visibility V / V

The weekend was surprisingly clear for a couple of nights and I got to test a new telescope on this distant galaxy, also known as M31. The distance to Andromeda is 2.5 million light-years. The figure also shows the companion galaxies M32 and M110.

      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.
