M31 - 18.8.2015 at 23.30 - 19.8.2015 at 02.30 Iitti Observation number 41264

Visibility IV / V

Awesome filming must now be fully utilized. Yes it is but it must be believed that the more squares, the better the image. Last night went as the camera shook at night until the battery ran out. Because the focus was not quite right, the subject had time to crawl somewhat in the image area. So I had to rough out the last 70 pictures. Compared to my own skill level, I am happy with this.

      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.
